PROBLEM TO BE SOLVED: To easily and safely attach/detach a photoreceptor drum to/from a main body of a device in its axial direction while protecting its photoreceptive face. SOLUTION: Movable shafts 133, each sandwiching a cushioning medium 132, are disposed in at least three areas on the peripheral face of the photoreceptor drum 10 in the axial direction. When a front lid F is attached, the actuation pin 135 of each actuation lever 134 integrated with the movable shaft 133, is pressed by the square hale H of the front lid F to separate the cushioning medium 132 from the peripheral face of the drum, and it is held in the position by the elastic force of a restriction plate 136. When the photoreceptor drum 10 is detached, the movable shaft 133 is turned counterclockwise by the operation of turning the front lid F counterclockwise to disengage a lock pin PL and a key-shaped hole HK from each other, and the cushioning medium 132 is brought into contact with the peripheral face of the drum and held in the state by the restriction plate 136. |
