Patent ID: 7858277

Claim:
A combination of a photosensitive body in contact with a prescribed elastic member, comprising: a photosensitive layer formed on a surface of the photosensitive body for being electrically charged and having an electrostatic latent image formed thereon by being exposed to light irradiation; wherein the prescribed elastic member is in contact with the photosensitive layer, and wherein said photosensitive layer has an initial dynamic friction coefficient μk 0 of 0.51 to 0.6 or less against the prescribed member, and wherein where a dynamic friction coefficient of said photosensitive layer against said prescribed member after a prescribed friction is given is defined as a dynamic friction coefficient μk 1 , and said photosensitive layer has a dynamic friction coefficient variation amount Δμk, as a difference between said initial dynamic friction coefficient μk 0 and said dynamic friction coefficient μk 1 , of 0.024 to 0.06.
