Abstract

PURPOSE:To prevent the damaging and deterioration of photoreceptor surface and perform the removal operation of transfer paper rapidly and easily by making a rotary drum removable without moving the same in the axial line direction. CONSTITUTION:A rotary drum 14 is inserted into the housing through the right end opening of the housing and each of a pair of non-sensitive regions 86 near the both side ends of the drum 14 is placed on each end part of the guide faces 96a and 96b of guide and support members 72a and 72b. Thence, when the drum 14 is moved by the specified amount toward fulcrum axis holes 90a, 90b, each of bearing members 78 comes to position on each of the guide faces 94a and 94b of the members 72a and 72b. Next, when the drum 14 is moved toward the fulcrum axis holes 90a, 90b by turning the members 78 on the guide faces 94a, 94b, the regions 86 go away from the guide faces 96a, 96b and the members 78 are positioned in the fulcrum axis holes 90a, 90b through notches 92a, 92b. In this way, the drum 14 is mounted rotatably and removably to the fulcrum axis holes 90a, 90b by way of the members 78.
