Abstract
An electrophotographic printing machine in which a light image exposing a non-uniform charge pattern formed on a photoconductive member is substantially attenuated to record a latent image thereon. Substantially unattenuated light rays discharge selected portions of the charge pattern. In this manner, fatigue of the photoconductive member is minimized.
