1. A process cartridge comprising:

  • an electrophotographic photosensitive drum;

    a drum flange fixed to one longitudinal end of said electrophotographic photosensitive drum;

    a coupling member that receives a rotating force for rotating said electrophotographic photosensitive drum and transmits the rotating force to said electrophotographic photosensitive drum through said drum flange;

    a first regulating portion that regulates movement of said electrophotographic photosensitive drum in a direction from the one longitudinal end of said electrophotographic photosensitive drum to the other longitudinal end of said electrophotographic photosensitive drum; and

    a second regulating portion that regulates movement of said electrophotographic photosensitive drum in a direction from the other longitudinal end of said electrophotographic photosensitive drum to the one longitudinal end of said electrophotographic photosensitive drum,wherein said drum flange has a first regulated portion capable of being regulated by said first regulating portion, a second regulated portion capable of being regulated by said second regulating portion, and a connecting portion that is connected with said coupling member so that a rotational axis of said coupling member is inclineable relative to a rotational axis of said drum flange.
