A cartridge includes a photosensitive drum and a developing roller configured to develop an electrostatic latent image formed on the photosensitive drum. A first frame rotatably supports the photosensitive drum and a second frame rotatably supports the developing roller. A movable member is movable with respect to the second frame, with the movable member including a first force receiving surface and a second force receiving surface. The second frame is movable relative to the first frame between a contact position in which the developing roller is in contact with the photosensitive drum and a spaced position in which the developing roller is spaced from the photosensitive drum. The second force receiving surface is capable of being moved by the first force receiving surface between a first position and a second position, and the second frame is capable of being moved by the second force receiving surface from the contact position toward the spaced position.

Process cartridge and image forming apparatus

A process cartridge is detachably mountable to a main assembly of an electrophotographic image forming apparatus. The cartridge includes an electrophotographic photosensitive drum, a developing roller, a drum unit containing the drum, a developing unit containing the roller and being movable so the roller contacts and is spaced from the drum, and a first force receiver receiving a force from a main-assembly first force applier by movement of a door from open to closed positions when mounting the cartridge and a second force receiver movable from a stand-by position by movement of the first force receiver by a force received from the first force applier. The second force receiver takes a projected position receiving a force from the second force applier to move the developing unit so the roller moves out of contact with the drum, the projected position being higher than the stand-by position.
