PURPOSE:To facilitate attachment and detachment of a photosensitive drum against the processing cartridge. CONSTITUTION:The whole of the device is integrated into a unit by attaching flanges on both sides of the photosensitive drum 3, providing rotational shafts protruding from these flanges, engaging bearing members to each rotational shaft, and attaching a gear 41. Supporting holes 6a and 6b are pierced on supporting members 6L and 6R on the right and the left of a case main body 2, and a chamfer 6c where the rotational shaft can be passed through is formed on one of the supporting holes 6a. The photosensitive drum 3 is supported feely rotatably by fitting the bearing member of the photosensitive drum unit to the supporting holes 6a and 6b. Because the rotary shaft can be passed through the chamber 6c when the photosensitive drum unit is attached or detached from the case main body 2 of the photosensitive drum unit, the device can be made into a unit, and the attachment time is shortened. |
