摘要： An electrophotographic photosensitive drum is for a process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus. The main assembly includes a motor, and a gear having a non-circular twisted hole. The drum includes a cylinder having a non-circular twisted projection engageable with the hole to receive a driving force from the main assembly when the cartridge is mounted to the main assembly. A recess is formed in of the projection and has a bottom portion and a side surface portion. When the projection receives a pulling force toward the hole by rotation of the gear with the projection and the hole being engaged with each other, the bottom portion contacts a spherical surface portion provided at a central portion of the hole, and the side surface portion contacts the spherical surface portion.

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.
