    摘要： An electrophotographic image forming process includes the steps of charging, light exposure, reversal development, and image transfer, using a photoconductor having an electroconductive support, and a photo-conductive layer formed thereon, with a residual solvent being contained in the photoconductor, and the electrophotographic photoconductor showing a residual potential change ratio of 200% or less, a sensitivity change ratio of 30% or less, and an electrostatic capacity change ratio of 30% or less. The photoconductor for use with the above-mentioned image forming process is also disclosed.

    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.
