Abstract
A photosensitive member used for an electrophotographic copying process includes an electrically conductive layer and a photosensitive layer formed thereon. The photosensitive layer has a surface region which is subject to an imagewise exposure to form an electrostatic latent image thereon which corresponds to an effective image area on an original which is to be copied. An area of the photosensitive layer other than the surface region which corresponds to the effective image area to be copied represents a photosensitive layer portion which substantially functions as a photosensitive member during a copying process, for example, during a charging step. The photosensitive layer portion is provided with a layer of an electrically conductive material.
