摘要：
A process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus, includes a first frame; a second frame coupled with the first frame for rotation about a shaft; an electrophotographic photosensitive drum provided in the first frame; a developing member, provided in the second frame, for developing an electrostatic latent image formed on the photosensitive drum with a developer; a developing member, provided in the second frame, for developing an electrostatic latent image formed on the photosensitive drum with a developer; an elastic member for applying an elastic force between the first frame and the second frame to urge the developing member to the photosensitive drum; a force receiving portion, provided downstream of the shaft with respect to a mounting direction in which the process cartridge is mounted to the main assembly of the image forming apparatus, for receiving a force from the main assembly of the image forming apparatus to keep the developing member away from the photosensitive drum when the process cartridge is mounted to the main assembly of the image forming apparatus; and a limiting portion for limiting upward movement of the first frame.
