ABSTRACT:
A photoreceptor for contact charging to be used in an electrophotographic process, which includes an electrically conductive base and a photosensitive layer formed on the base so as to be charged by contact charging, and is characterized in that even when pin holes or photosensitive layer lacking portions in the form of pin holes are present on he photosensitive layer, short-circuiting is safely and positively prevented over a long period. The electrically conductive base further includes a base main body of aluminum alloy having Brinell hardness higher than 40 H.sub.B, and an alumite treatment applied over the surface of the aluminum alloy base main body.
