<P>PROBLEM TO BE SOLVED: To provide a photosensitive drum unit capable of suppressing a deflection of a photosensitive drum and suppressing fluctuation in deflections among photosensitive drums. <P>SOLUTION: This photosensitive drum unit includes; a cylindrical photosensitive drum (11), and cylindrical damping members (20 and 30) fixed to the cylindrical inside of the photosensitive drum without sliding. The cylindrical outer peripheral surface of each damping member comes into contact with the inner face of the photosensitive drum across the entire axial length, and both the axial cylindrical ends of the damping member are formed to have different external diameters. The plurality of damping members are disposed in the axial direction of the photosensitive drum, and the adjacent damping members are so disposed that the sides thereof having large diameters are prevented from facing each other. <P>COPYRIGHT: (C)2012,JPO&INPIT |
