Abstract
The present invention provides an electrophotosensitive material comprising a conductive substrate and a photosensitive layer provided on the conductive substrate, wherein the photosensitive layer contains a polyarylate having a repeating unit represented by the general formula (1):wherein X represents a phenylene group, a naphthylene group, or a biphenylene group, as a binder resin. The polyarylate is contained in the amount of 30% by weight or more based on the entire binder resin. The electrophotosensitive material of the present invention have improved wear resistance and gas resistance while reconciling both characteristics, and thus longer life has been achieved.
