ABSTRACT:
An electrophotographic printing machine is provided with a photoreceptor whereon a transparent electrically conductive layer and a photoconductive layer are successively formed. A visible image is formed on the photoconductive layer by exposing the photoconductive layer while applying a voltage across toner supplied onto the surface of the photoreceptor and the transparent electrically conductive layer. The exposing energy of the exposure unit is set so as to satisfy an equation:
