ABSTRACT:
An electrophotographic system is described in which a photoconductive ion modulator screen is used in conjunction with an anodized aluminum dielectric imaging surface. This combination enables the steps of image transfer and fixing to be carried out simultaneously without destroying the latent image produced on the dielectric imaging surface.
A duplex anodized aluminum coating is prepared by forming a porous aluminum oxide layer by electrolytically oxidizing an aluminum surface and thereafter continuing the electrolytic oxidation under conditions which produce a barrier type aluminum oxide layer. The resulting duplex anodized aluminum coating containing both porous type aluminum oxide and barrier type aluminum oxide is used as the dielectric imaging surface in this electrophotographic system.
