Abstract:
A process cartridge detachably mountable on a main assembly of an electrophotographic image forming apparatus having laser beam emitting means to emit a laser beam, a laser shutter moveable between a shutting position to shut an optical path of the laser beam emitted from the laser beam emitting means and an opening position to retreat from the shutting position for allowing passage of the laser beam, and a moving member to move the laser shutter from the shutting position to the opening position, said process cartridge comprising:a cartridge frame;an electrophotographic photosensitive member;a driving force receiving member for receiving a rotation driving force for said electrophotographic photosensitive member from the main assembly of the apparatus when said process cartridge is mounted to the main assembly of the apparatus;process means acting on said electrophotographic photosensitive member;a first contact part provided on said cartridge frame to determine a position of said process cartridge relative to the main assembly of the apparatus by contacting a fixing member provided on the main assembly of the apparatus when said process cartridge is mounted to the main assembly of the apparatus; anda second contact part provided on said cartridge frame adjacent said first contact part in a direction intersecting a mounting direction along which said process cartridge is to be mounted to the main assembly of the apparatus, wherein said second contact part comes into contact with the moving member to move the laser shutter from the shutting position to the opening position and the moving member moves along the surface of said second contact part when said process cartridge is mounted to the main assembly of the apparatus.
