PURPOSE:To easily execute attaching/detaching operation even though the shaft line of a photosensitive drum is not aligned with the shaft of a driving shaft when the photosensitive drum is attached to and detached from the driving shaft, and to prevent backlash in the driving of the drum. CONSTITUTION:The driving shaft 5 is attached to the supporting frame 1 of an electronic copying machine through a bearing 3 on a fixed side, and the photosensitive drum is attached to the driving shaft 5. As to a photosensitive body assembling body 10, a bearing member 20 is attached to the center part of the flange member 15 on the fixed side of a drum member 11, and provided so that it can oscillate with respect to the flange member. Even when the shaft line of the drum is inclined against the driving shaft when the photosensitive body assembling body is attached to and detached from the driving shaft, the bearing member follows to oscillate. |
