Abstract

A cartridge that can be inserted in an apparatus main body of an image forming apparatus by moving along an axial direction of an image bearing member includes the image bearing member, a frame configured to support the image bearing member, a storage member configured to store therein information on the cartridge, and include an electrical contact, and a first pressed section and a second pressed portion configured to be pressed by the apparatus main body. The electrical contact is disposed between the first pressed section and the second pressed section, and is configured to be in contact with the main body contact on a lower side in a state where the cartridge is attached to the apparatus main body.

First claim

What is claimed is:

1. A cartridge capable of being inserted in an apparatus main body of an image forming apparatus by moving along an axial direction of an image bearing member, the cartridge comprising:
the image bearing member;
a frame configured to support the image bearing member;
a storage member configured to store therein information on the cartridge, and include an electrical contact that is configured to contact a main body contact provided to the apparatus main body;
a first pressed section configured to be pressed by the apparatus main body in such a manner that the cartridge is positioned with respect to the apparatus main body; and
a second pressed section configured to be pressed by the apparatus main body in such a manner that the cartridge is positioned with respect to the apparatus main body,
wherein the storage member is provided to the frame, and
wherein the electrical contact is disposed between the first pressed section and the second pressed section in the axial direction, and is configured to be able to be in contact with the main body contact on a lower side in a state where the cartridge is attached to the apparatus main body.

2. A cartridge capable of being inserted into an apparatus main body of an image forming apparatus by moving along an axial direction of a developer-carrying member, the cartridge being configured to be inserted into the apparatus main body separately from a unit including an image bearing member, the cartridge comprising:
the developer-carrying member configured to develop a latent image formed on the image bearing member;
a developing frame configured to support the developer-carrying member; and
a storage member configured to store therein information on the cartridge, and include an electrical contact that is configured to contact a main body contact provided to the apparatus main body,
wherein the storage member is provided to the developing frame, and
wherein the electrical contact is configured to be in contact with the main body contact on a lower side in a state where the cartridge is attached to the apparatus main body.

3. A cartridge capable of being inserted in an apparatus main body of an image forming apparatus by moving along an axial direction of an image bearing member, the cartridge comprising:
the image bearing member;
a frame configured to support the image bearing member;
a storage member configured to store therein information on the cartridge, and include an electrical contact that is configured to contact a main body contact provided to the apparatus main body;
a first pressed section configured to be pressed by the apparatus main body in such a manner that the cartridge is positioned with respect to the apparatus main body; and
a second pressed section configured to be pressed by the apparatus main body in such a manner that the cartridge is positioned with respect to the apparatus main body,
wherein the storage member is provided to the frame, and
wherein the electrical contact is between the first pressed section and the second pressed section in the axial direction, and faces toward a direction crossing the axial direction.

4. The cartridge according to claim 1 , wherein the electrical contact, the first pressed section, and the second pressed section are pressed upward when the cartridge is attached to the apparatus main body.

5. The cartridge according to claim 1 , wherein the storage member is disposed in a recess formed on the frame, the recess being recessed toward the image bearing member from a plane connecting between the first pressed section and the second pressed section.

6. The cartridge according to claim 1 , wherein a distance from a plane connecting between the first pressed section and the second pressed section to a plane on which the electrical contact is disposed is equal to or larger than 3 mm and equal to or smaller than 20 mm.

7. The cartridge according to claim 1 , wherein the storage member includes a plurality of the electrical contacts arranged in a direction crossing the axial direction.

8. The cartridge according to claim 1 , wherein when the cartridge is equally divided into three divided areas in the axial direction, the storage member is disposed on a center one of the divided areas.

9. The cartridge according to claim 1 , further comprising a charging member configured to charge a surface of the image bearing member,
wherein the electrical contact is disposed on an inner side more than both end portions of the charging member in the axial direction.

10. The cartridge according to claim 1 , wherein the electrical contact is disposed on an inner side more than both end portions of an area, in which the image bearing member is exposed by an exposing device in the apparatus main body, in the axial direction.

11. The cartridge according to claim 1 , further comprising:
a first restricting section configured to restrict a position of the main body contact in the axial direction; and
a second restricting section configured to restrict a position of the main body contact in a direction crossing the axial direction.

12. The cartridge according to claim 1 , further comprising a cartridge guide protruding in a direction crossing the axial direction and extending along the axial direction.

13. The cartridge according to claim 12 , wherein the electrical contact is disposed in an intermediate portion of the cartridge guide.

14. The cartridge according to claim 1 , further comprising:
a first positioned section configured to come into contact with a positioning section of the apparatus main body and disposed on one end of the image bearing member in the axial direction; and
a second positioned section configured to come into contact with a positioning section of the apparatus main body and disposed on another end of the image bearing member in the axial direction,
wherein the first pressed section and the second pressed section are disposed between the first positioned section and the second positioned section.

15. A process cartridge comprising:
a developer-carrying member configured to carry a developer; and
the cartridge according to claim 1 .

16. An image forming apparatus comprising:
the cartridge according to claim 1 configured to be detachably attached to the image forming apparatus; and
a developing cartridge including a developer-carrying member configured to develop a latent image formed on the image bearing member, the developing cartridge being detachably attached to the image forming apparatus separately from the cartridge according to claim 1 .

17. The cartridge according to claim 3 , wherein the electrical contact, the first pressed section and the second pressed section are pressed upward when the cartridge is attached to the apparatus main body.

18. The cartridge according to claim 3 , wherein the storage member is disposed in a recess formed on the frame, the recess being recessed toward the image bearing member from a plane connecting between the first pressed section and the second pressed section.

19. The cartridge according to claim 3 , further comprising a charging member configured to charge a surface of the image bearing member,
wherein the electrical contact is disposed on an inner side more than both end portions of the charging member in the axial direction.

20. The cartridge according to claim 3 , further comprising a cartridge guide protruding in a direction crossing the axial direction and extending along the axial direction, wherein the electrical co
