Abstract
An electrophotographic process comprising the steps of providing a composite photosensitive member consisting of a conductor, an intermediate layer of organic insulator, a photoconductive semiconductor layer as a charge generating layer formed on the conductor and a transparent photo semiconductor layer as a charge retentive and transporting layer; forming on the composite photosensitive member an electrostatic latent image corresponding to an image of a document to be copied; obtaining desired number of duplicated copies; uniformly charging the composite photosensitive member simultaneously with or before exposing ultraviolet rays on the composite photosensitive member to release charges trapped in the composite member.
