Abstract
An electrophotographic copying apparatus comprises a photosensitive member which includes a conductive layer carrying a sequential lamination of a first photoconductive layer which is sensitive to visible light and a second photoconductive layer which is sensitive to ultraviolet rays and serves as an insulator to the visible light and a neutralizing unit for an irradiation of visible light and ultraviolet ray in order to neutralize charge on an area beyond image scope of the photosensitive member.

An electrophotographic copying apparatus including a photosensitive member which includes a conductive layer carrying a sequential lamination of a first photoconductive layer which is sensitive to visible light and a second photosensitive layer which is sensitive to ultraviolet radiation and serves as an insulator to the visible light, said photosensitive member on which is formed an electrostatic latent image being repeatedly conveyed to a developing station and a transfer station in sequential fashion to produce a plurality of copies with said electrostatic latent image which has been formed thereon, the apparatus characterized by provision of neutralizing means for an irradiation of the conductive layer with visible light and ultraviolet rays to neutralize charge on an area beyond image scope of the photosensitive member, said neutralizing means being disposed upstream of the developing station and downstream of the transfer station, as viewed with regard to a direction of the conveyance of the photosensitive member.
