PURPOSE:To prevent vibration from being generated in the case of drive transmission by providing a port to insert a driving shaft to the flange of a photosensitive drum and a member to be driven and arranging a central through hole, through which the driving shaft is passed, and a pawl insertion recessed part to radially engage a pawl for driving from the central through hole in the member to be driven. CONSTITUTION:At the central part of a flange 12 provided on the side of mounting a photosensitive drum 11, a hole 13 for mounting is provided and on the driving part side of the flange 12 in the photosensitive drum 11, a member 15 to be driven is provided. This member 15 to be driven is equipped with a central through hole 16, to which a driving shaft 20 is inserted, and pawl insertion recessed parts 18... to which the pawls for driving are inserted. When mounting a photosensitive unit 10 to a picture forming device, this photosensitive unit 10 is mounted so that the driving shaft 20 fixed to the frame of a main body can be inserted to the hole 13 formed on the flange 12 of the photosensitive drum 11, and the photosensitive drum 11 is exactly positioned to the driving shaft 20. Thus, the vibration is prevented from being generated in the case of drive transmission. |
