Abstract of the Disclosure An electrophotographic photoconductor, formed on a conductive substrate by spray pyrolysis, comprising essentially a major amount of cadmium sulphide and a minor amount of zinc sulphide. The cadmium layer is at least three microns in thickness and is formed in three zones. The zone adjacent the metal substrate adapted to form a contact layer, bears an amount of lead sulphide; the outermost zone, adapted to absorb light, is doped with a minor amount of copper to eliminate fatigue and the intermediate zone which is necessary to increase the surface potential is adapted to transport light-generated charge and is doped with a minor amount of chlorine. The process is carried on in the atmosphere with three different aqueous solutions of reagents to form the three different zones. The photoconductive layer is micro-crystalline in structure and bears adsorbed oxygen.
