Abstract

A method and apparatus of electrophotography wherein before exposure of a photosensitive element to a light image the element is subjected to a substantially uniform light irradiation to release a part of the charge carriers trapped in a photoconductive layer of the element, thereby controlling the potential of a latent image to be formed on the element within a range fit for the development of the latent image.
