Abstract

A cartridge detachably mountable to a main assembly of an image forming apparatus having a main assembly electric contact includes: a contact member for receiving pressure by the main assembly electric contact, wherein the contact member has a first surface as a contact portion for receiving the pressure by the main assembly electric contact and has a second surface bent from the first surface toward a side opposite from a side where the main assembly electric contact is provided; a holding member for holding the contact member; a portion to be limited provided at an end of the second surface; and a limiting portion, provided on the holding member, for limiting movement of the portion to be limited.

First claim

What is claimed is:

1. A cartridge detachably mountable to a main assembly of an image forming apparatus having a main assembly electric contact, the main assembly electric contact being non-detachably attached to the main assembly, said cartridge comprising:
a contact member for receiving pressure by the main assembly electric contact, wherein said contact member has a first surface as a contact portion for receiving the pressure by the main assembly electric contact, a second surface bent from the first surface toward a first side opposite from a second side, the second side being where the main assembly electric contact is provided, and a bent portion which is a boundary between the first surface and the second surface;
a holding member for holding said contact member;
a portion to be limited provided at an end of the second surface; and
a limiting portion, provided on said holding member, for limiting movement of said portion to be limited, wherein the first surface is not supported by said holding member from the first side, and
wherein a cut-away portion is formed in the bent portion, a part of the first surface, and a part of the second surface, and a cut and erected portion is formed in the second surface by cutting and erecting an end portion of the cut-away portion, at the second surface, toward said portion to be limited.

2. The cartridge according to claim 1 , further comprising:
process means for being energized from said contact member, and
urging means for urging said process means in a predetermined direction,
wherein said contact member has a third surface opposite from the second surface, and
wherein the third surface is urged toward said holding member by said urging means.

3. The cartridge according to claim 2 , wherein said process means is a developing roller having a shaft, and
wherein said urging means urges said developing roller in an axial direction of said developing roller.

4. The cartridge according to claim 1 , wherein said contact member has a third surface opposite from the second surface and a fourth surface, opposite from the second surface, bent from the first surface toward a side opposite from the side where the main assembly electric contact is provided, and
wherein the third surface is formed by being bent from the fourth surface.

5. The cartridge according to claim 1 , further comprising an electrophotographic photosensitive member.

6. An image forming apparatus comprising:
the cartridge according to claim 1 ; and
the main assembly electric contact provided so as to be capable of being pressed against said contact member.
