PURPOSE:To prevent the occurrence of a scratch on a photosensitive body surface with the rolling off of a drum even when a load is applied to the drum with the bending of a paper due to the jamming of the paper in the vicinity of the drum by mounting a photosensitive drum with the freedom degree to a drum receiving part. CONSTITUTION:Bearing members 19 and 20 have a bearing at the central part, and a housing as a whole has the shape in which the surface along the direction to insert it toward bearing member holders 21 and 22 comes to be a plane. On the other hand, receiving parts 23 and 24 of the bearing receiving members 21 and 22 are formed in a U-shaped way approximately, and at the inside surface, a roller bearing 25 is provided. When the bearing member holders 21 and 22 are inserted into the receiving parts 23 and 24, both are engaged through the roller bearing 25, and the smooth shifting can be executed along the direction of the receiving parts 23 and 24. Thus, the photosensitive drum 1 is equipped with the degree of freedom along the inserting direction of the receiving parts 23 and 24 and the shifting of a rotary shaft center can be executed. |
