Abstract
An electrophotographic process including the step of pre-exposing the surface of a photosensitive member to light at an exposure of no less than 10.sup.3 lx-sec, followed by the uniform charging of the same. The photosensitivity of this type photosensitive member in an image exposing step varies according to its prior history. This process further includes the step of exposing an image by projecting an optical image, corresponding to an original image, onto the photosensitive member thus charged for forming a clear electrostatic latent image, corresponding to the original image, on the surface of the photosensitive member.
