A process cartridge, which is detachably mountable to an image forming apparatus main body, includes: an electrophotographic photosensitive drum; a process member acting on the electrophotographic photosensitive drum; a rotation fulcrum portion which constitutes a supported portion of the process cartridge, the supported portion being supported by the image forming apparatus main body when attached to the image forming apparatus main body and which is parallel to the electrophotographic photosensitive drum; and an abutting portion which is spaced apart from the rotation fulcrum portion and which moves when the process cartridge is rotated around the rotation fulcrum portion when the process cartridge is mounted to the image forming apparatus main body to thereby enable a laser beam shielding mechanism provided in the image forming apparatus main body. |
