Patent attributes
A process cartridge comprises an electrophotographic photosensitive drum and a developing roller. A coupling member is provided that receives a rotating force for rotating the electrophotographic photosensitive drum and transmits the rotating force to the electrophotographic photosensitive drum through a drum flange. The drum flange has (i) a first regulated portion capable of being regulated by a first regulating portion, (ii) a second regulated portion capable of being regulated by a second regulating portion, (iii) a connecting portion that is connected with the coupling member so that a rotational axis of the coupling member is inclineable relative to a rotational axis of the drum flange, and (iv) a gear portion that transmits the rotational force from the coupling member to the developing roller.
