Multi-layered electrophotographic imaging member having a composite photoconductive insulating film wherein one layer of said film comprises a photoconductive material capable of substantial spectral response in the visible region of the electromagnetic spectrum, and a second layer of an electronically active insulating polymeric material, contiguous with said photoconductive layer, which is transparent, capable of facile transport of electrons which are injected into it upon photoexcitation of the contiguous photoconductive layer and yet incapable of substantial spectral response within the wavelength of primary photoresponse of the contiguous photoconductive layer.
