ABSTRACT:
A flexible metal printing cylinder having a coating of a crystalline photoconductive material thereon. The cylinder is an electrodeposited sleeve of nickel or similar material that is a fraction of a millimeter in thickness which is adapted to be mounted in a printing press in order to enable the press to print electrostatically. The coating is applied by r.f. sputtering and comprises a thin film layer of the order of about 2000 to 6000 Angstroms thick of a wholly inorganic, electronically anisotropic, crystalline, flexible, high gain photoconductive material, as for example ultrapure cadmium sulfide. The cylinder may have an image adhered to its surface which is of dry insulating toner.
