Abstract
An electrophotographic photoconductor has an electroconductive support and a photoconductive layer formed thereon, a surface top portion of the photoconductor containing a high-molecular charge transport material including a polycarbonate copolymer synthesized from (a) a bisphenol monomer with an ionization potential of 6.0 eV or less, having a positive hole transporting function, and (b) a bisphenol monomer having a substituent at the o-position with respect to at least one hydroxyl group thereof, the substituent being bulkier than a fluorine atom. A process cartridge holds the above-mentioned photoconductor therein, and an electrophotographic image forming apparatus is provided with the above-mentioned photoconductor or process cartridge.
