PURPOSE:To save a space so as to miniaturize an image forming device by housing a fly wheel in a photosensitive drum. CONSTITUTION:The fly wheel 3 is attached in the photosensitive drum 1 and integrally rotates with the drum 1. When the wheel 3 is housed in the space 2a of a flange 2, it is surely attached by being screwed in the screw hole 2c of the flange 2 with a screw 4 through a screw hole 3a after the rotary shaft 2b of the flange 2 is inserted in the shaft hole 3b of the wheel 3. Since the fly wheels 3 and 3 are attached in the photosensitive drum 1, the space in the axial direction of the drum 1 is not needed and the device is miniaturized. |
