Process cartridge that spaces a developing roller and photosensitive drum from each other and image forming apparatus usable therewith

A process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus, the electrophotographic image forming apparatus including a first engageable member movable between a first position and a second position retracted from the first position and a second engageable member movable between a third position and a fourth position retracted from the third position, said process cartridge being transportable while being in a mounted state in the main assembly of the electrophotographic image forming apparatus, said process cartridge comprising:

• an electrophotographic photosensitive drum;
• a developing roller that develops an electrostatic latent image formed on said electrophotographic photosensitive drum;
• a first frame supporting said electrophotographic photosensitive drum;
• a second frame supporting said developing roller, said second frame being movably connected with said first frame;
• a first force receiving portion that receives, from the first engageable member, a force for separating said electrophotographic photosensitive drum and said developing roller from each other by contacting to the first engageable member, when said process cartridge is mounted to the main assembly of the electrophotographic image forming apparatus, and the first engageable member is placed at the first position;
• a second force receiving portion that maintains said electrophotographic photosensitive drum and said developing roller spaced from each other and that receives a force, from the second engageable member, for separating the first engageable member and said first force receiving portion from each other by contacting said second engageable member when said process cartridge is mounted to the main assembly of the electrophotographic image forming apparatus, and the second engageable member is placed at said third position;
• wherein when said process cartridge is transported while being in a mounted state in said main assembly of the electrophotographic image forming apparatus, said second force receiving portion receives a force for separating the first engageable member and said first force receiving portion from each other from the second engageable member, and
• wherein said first force receiving portion and said second force receiving portion are disposed at the positions which are different from each other.
