PURPOSE:To increase dot splitting effect and to attain tone reproduction by forming recessed and projecting parts on a contact surface of a drum base with a photosensitive body. CONSTITUTION:The part of the photosensitive drum base 2 in contact with the photosensitive body is provided with the innumerable recessed parts 2a and projecting parts 2b, whereby the dot splitting effect of the photosensitive drum body is increased. As a result, the photosensitive drum of the electrophotographing machine comes to have high tone reproduction. |
