ABSTRACT:
An endless belt or cylinder in which the base or substrate is a conductive member and there is a coating of a wholly inorganic, microcrystalline, high quantum yield, electronically anisotropic photoconductive material on the substrate. The coating is capable of being charged and thereafter exposed to radiant energy from an object such as a scene or pattern for selectively discharging the coating and providing a latent image of the object on the coating. The latent image can thereafter be developed by toner and transferred to a receptor such as a sheet of paper, cloth and the like.
The belt may be formed of highly flexible synthetic organic resin such as polyester or the like and in such case the coating will be deposited onto an intervening thin layer of an ohmic material.
The cylinder may be a relatively rigid one of metal.
The coating may be cadmium sulfide.
The method of making the cylinder or belt comprises forming the cylinder or belt and placing same in a sputtering apparatus and r.f. sputtering the coating onto the surface of the cylinder or belt.
