Abstract:
1. A process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus, the main assembly including an opening, a door movable between a close position for closing the opening and an open position for opening the opening, a first force application member movable with movement of the door from the open position to the close position and a second force application member movable by a driving force from a driving source, said process cartridge comprising: an electrophotographic photosensitive drum; a developing roller configured and positioned to develop an electrostatic latent image formed on said electrophotographic photosensitive drum; a drum frame supporting said electrophotographic photosensitive drum; a developing frame which supports said developing roller and which is movable relative to said drum frame such that developing roller is movable between a contact position in which said developing roller contacts said electrophotographic photosensitive drum and a spaced position in which said developing roller is spaced from said electrophotographic photosensitive drum; and a force receiving device including a first force receiving portion configured and positioned to receive a force from the first force application member by movement of said door from the open position to the close position in the state that said process cartridge is mounted to the main assembly of the apparatus through the opening, and a second force receiving portion movable relative to said developing frame to an operative position from a retracted position retracted from the operative position by movement of said first force receiving portion by a force received from the first force application member, wherein said second force receiving portion takes the operative position for receiving a force from the second force application member to move said developing frame from the contact position to the spaced position, wherein said second force receiving portion takes the retracted position for permitting said process cartridge to enter said main assembly.
