Electrophotographic photoconductor and electrophotographic copying process and apparatus using the photoconductor

摘要

An electrophotographic photoconductor comprises (a) an electroconductive support, (b) a photoconductive layer formed thereon comprising a selenium alloy, and (c) a protective layer which is formed on the photoconductive layer, contains a binder resin component and an anti-oxidizing agent. In an electrophotographic copying process and an electrophographic copying apparatus using this photoconductor, the protective layer is abraded at a predetermined rate during the copying process in such a fashion that the anti-oxidizing agent contained in the protective layer is always present at the surface of the protective layer, thereby protecting the photoconductor from ozone and ions which are generated during corona charging of the photoconductor.
