PURPOSE:To prevent an image carrier drum from moving in the radial direction to prevent its damage and to improve the recording quality by not elastically but rigidly detaining the image carrier drum in the radial direction. CONSTITUTION:When a photosensitive body 2a is suspended by a grip 13 and one detaining member 3a is lowered along a guide rail 10, one detaining member 3a is driven through a lever 12 by a spring 11 as shown by a arrow and a notched part 31 is engaged with the other detaining member 5a when the photosensitive body 2a is received by a reception base 4a. As the result, movement in the radial direction of the photosensitive body 2a is rigidity suppressed by one detaining member 3a, the reception base 4a, and the other detaining member 5a. Thus, the photosensitive body 2a is surely prevented from moving in the radial direction to prevent the damage of the photosensitive surface, development defects, transfer defects, or the like. |
