Abstract:
A process cartridge is detachably mountable to a main assembly of an electrophotographic image forming apparatus. The cartridge includes a photosensitive drum, and a developing roller for developing a latent image. A development coupling portion is provided adjacent to one axial end of the developing roller, with the development coupling portion including an engaging portion configured and positioned (a) to receive a driving force for rotating the developing roller, and (b) to be movable in a direction crossing the axis of the developing roller relative to the developing roller. The cartridge also includes an urging portion configured and positioned to urge the engaging portion in a direction crossing the axis of the developing roller. Also, an abutting portion is configured and positioned so that movement of the engaging portion can be prevented when the engagement portion has not established engagement with a development coupling member of the main assembly.
