Abstract

Photoconductors for use in xerographic copiers conventionally are comprised of several layers of different material. In one such photo-conductor configuration the layers include a MYLAR* substrate with a very thin layer (1,000 Angstroms) of aluminum coated thereon. Over the aluminum is coated a thin barrier layer which in turn has coated thereon a charge generation layer. Finally, a charge transport layer is coated over the charge generation layer. The photoconductor is formed into a roll and installed in the xerographic copier. The photoconductor is incrementally advanced, as needed, to provide fresh photoconductor surface.
