Process cartridge and electrophotographic image forming apparatus

An electrophotographic image forming apparatus for forming an image on a recording material, wherein a process cartridge is detachably mountable to said electrophotographic image forming apparatus, said electrophotographic image forming apparatus comprising:

• (a) a mounting device configured and positioned to detachably mount the process cartridge, the process cartridge including, an electrophotographic photosensitive drum, a process device actable on the electrophotographic photosensitive drum, a drum shutter movable between a close position in which the drum shutter covers an exposed portion of the electrophotographic photosensitive drum which is exposed through the cartridge frame and an open position in which the drum shutter is retracted from the close position to expose the portion of the electrophotographic photosensitive drum, the drum shutter having a first shutter portion rotatably supported on the cartridge frame and a second shutter portion rotatably supported on the cartridge frame, wherein in the close position, the first shutter portion covers an upstream side of the exposed portion with respect to an opening direction in which the drum shutter moves from the close position to the open position, and the second shutter portion covers a downstream side of the exposed portion with respect to the opening direction, wherein the downstream side of the exposed portion is downstream of the upstream side of the exposed portion, and wherein in the open position, the first shutter portion and the second shutter portion overlap each other in the widthwise direction of the drum shutter;
• and
• (b) a feeding device configured and positioned to feed the recording material.
