Process cartridge and image forming apparatus

摘要

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.

主权项

1. A cartridge comprising:
a frame; a developing roller rotatably supported by said frame; a coupling member provided at one longitudinal end of said frame and configured to receive a driving force; a gear provided at the one longitudinal end and configured to receive the driving force from said coupling member; a covering member provided at the one longitudinal end and configured to cover said gear; a movable member provided at the one longitudinal end and movable relative to said frame; and an urging member urging said movable member, wherein said movable member includes a projected portion capable of projecting beyond said covering member, and said movable member is movable between a first position in which said projected portion projects beyond said covering member and a second position in which said projected portion is closer to said frame than in the first position, wherein said movable member is movable from the first position to the second position by an urging force of said urging member, and wherein, when said movable member is in the first position, said movable member is rotatable about an axis parallel with a longitudinal direction of said frame.
