PURPOSE:To reduce 'squeak' without deteriorating the cleaning capacity of a cleaning blade by absorbing a sound generated in a photosensitive drum, by forming a specific sound absorbing layer on the inside surface of a cylindrical base can body for constituting a base body of a photosensitive drum. CONSTITUTION:A photosensitive drum 2 is provided with a cylindrical base can body 3, a photosensitive layer 4 which has been formed on the outside surface of this base ban body, and a sound absorbing layer 5 which can absorb a sound generated in the inside of the photosensitive drum 2 due to a vibration of a cleaning blade 11, by being formed on the inside surface of its base can body. The sound absorbing layer 5 is formed on the inside surface of the photosensitive drum 2 by a one liquid type paint whose main component is an acryl resin, and can absorb a sound generated in the inside of the photosensitive drum 2 due to a vibration of the cleaning blade 11 by unevenness of the surface of the sound absorbing layer 5, therefore, after all, a sound of the whole photosensitive drum 2 is reduced, and generation of 'squeak' of the blade 11 accompanied with a discomfort sense can be prevented. |
