FIELD: physics, photography.SUBSTANCE: invention relates to a process cartridge and an electrophotographic image forming apparatus in which the process cartridge is detachably installed. The disclosed process cartridge comprises an electrophotographic photosensitive drum, a developing roller which develops a latent image provided on said electrophotographic photosensitive drum, a drum flange mounted at one end of said electrophotographic photosensitive drum, a connecting element which receives a rotary force for rotating said electrophotographic photosensitive drum and transmits the rotary force the electrophotographic photosensitive drum through said drum flange, a first control part which controls movement of said electrophotographic photosensitive drum in a direction from one longitudinal end to another longitudinal end of said electrophotographic photosensitive drum, and a second control part which controls movement of said electrophotographic photosensitive drum in a direction from the other longitudinal end to said one longitudinal end of said electrophotographic photosensitive drum, wherein said flange has (i) a first controlled part adapted to be controlled by said first control part, (ii) a second control part adapted to be controlled by said second control part, (iii) a connection part which is connected to said connecting element, such that the axis of rotation of said connecting element can be inclined relative to the axis of rotation of the drum flange, and (iv) a toothed part which transmits a rotary force from said connection element to said developing roller.EFFECT: high accuracy of positioning the cartridge.6 cl, 34 dwg |
