摘要： An electrophotographic apparatus includes a movable photosensitive member having a photoconductive layer, and a charging member for charging the photosensitive member. A latent image forming device forms an image on the photosensitive member, and an electric charge applying device applies an electric charge of a polarity opposite from a charging property of the charging member to the photosensitive member. The photosensitive member includes a rectifying layer on the photoconductive layer to provide, at an interface between the photoconductive layer and the rectifying layer, a p-n junction preventing electric charge of the opposite polarity from entering the photoconductive layer.

Then, disturbance to the image by the image transfer operation can be avoided.
