Abstract

Provided is a developer container that accommodates developer, including: a first frame that has a recessed portion; and a second frame that has a first protruding portion, wherein the first frame and the second frame are joined by a first adhering portion in which the recessed portion and the first protruding portion are welded together, and a second adhering portion in which a second protruding portion and a flat portion are welded together, the recessed portion having a positioning inner side face that performs positioning of the first frame and the second frame within a recessed portion. Also provided are a method to manufacture a developer container, a developing apparatus having the developer container, a cleaning apparatus, a process cartridge, and an image forming apparatus.

First claim

What is claimed is:

1. A developer container that accommodates developer, comprising:
a first frame that has a recessed portion which has a sloped face; and
a second frame that has a first protruding portion;
wherein the first frame and the second frame are joined by
a first adhering portion in which the sloped face of the recessed portion and the first protruding portion are welded together, and
a second adhering portion in which a second protruding portion on one of the first frame and the second frame and a flat portion on the other side of the first frame and the second frame are welded together,

the recessed portion having a positioning inner side face that performs positioning of the first frame and the second frame.

2. A developer container according to claim 1 ,
wherein the second adhering portion is provided in a direction intersecting the direction in which positioning is performed by the positioning inner side face.

3. The developer container according to claim 2 ,
wherein the second adhering portion is provided in a direction that is orthogonal to the direction in which positioning is performed by the positioning inner side face.

4. The developer container according to claim 1 ,
wherein at least one of the recessed portion and the first protruding portion has a sloped face.

5. The developer container according to claim 1 ,
wherein the first frame comprises the second protruding portion, and the second frame comprises the flat portion.

6. The developer container according to claim 1 ,
wherein the first frame comprises the flat portion, and the second frame comprises the second protruding portion.

7. The developer container according to claim 1 ,
wherein the first adhering portion is configured such that the first protruding portion touches the inner side face for determination of the positional relation between the first frame and the second frame.

8. The developer container according to claim 1 ,
wherein the first adhering portion is welded as a shared joint.

9. The developer container according to claim 1 ,
wherein a plurality of first adhering portions are provided.

10. The developer container according to claim 9 , wherein the plurality of first adhering portions are provided on a same line.

11. The developer container according to claim 1 , wherein a region is provided in which a portion of the first adhering portion and a portion of the second adhering portion overlap.

12. The developer container according to claim 11 , wherein the first frame and second frame are joined continuously from the first adhering portion to the second adhering portion.

13. A developing apparatus comprising:
developer container according to claim 1 ; and
a developer bearing member to bear the developer.

14. An image forming apparatus,
wherein the developing apparatus according to claim 13 can be detachably mounted.

15. A cleaning apparatus comprising:
a cleaning device configured to remove remaining developer; and
the developer container according to claim 1 , to contain the removed developer.

16. A process cartridge comprising:
developer container according to claim 1 ; and
an image-bearing member for forming a developed image using developer contained in the developer container.

17. A method to manufacture a developer container to contain developer, comprising:
adhering together a first frame having a recessed portion which has a sloped face and a second frame having a first protruding portion;
wherein the adhering process further includes
a first process to adhere the sloped face of the recessed portion, which has a positioning inner side face to position the first frame and the second frame within the recessed portion, and the first protruding portion, and
a second process to adhere a flat portion on one of the first frame and the second frame and a second protruding portion on the other of the first frame and the second frame.

18. A developer container for containing developer, comprising:
a first frame that has a recessed portion; and
a second frame that has a first protruding portion which has a sloped face;
wherein the first frame and the second frame are joined together at:
a first adhering portion in which the recessed portion and the sloped face of the first protruding portion are adhered together, and
a second adhering portion in which a second protruding portion on one of the first frame and the second frame and a flat portion on the other of the first frame and the second frame are adhered together,
the recessed portion having a positioning inner side face that performs positioning of the first frame with respect to the second frame.
