ELECTROPHOTOGRAPHIC PHOTORECEPTOR, ELECTROPHOTOGRAPHIC CARTRIDGE AND ELECTROPHOTOGRAPHIC IMAGING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor excellent in durability as well as in stability and electrophotographic properties by using a CGM more excellent in stability to crystal transition, crystal growth and/or aggregation than a conventional CGM, and to provide an electrophotographic cartridge including the electrophotographic photoreceptor and an electrophotographic imaging apparatus including the electrophotographic photoreceptor. SOLUTION: The electrophotographic photoreceptor includes: an electrically conductive substrate; a charge generating layer formed on the electrically conductive substrate and comprisingμ-oxo-gallium phthalocyanine dimer as a charge generating material dispersed in a binder resin; and a charge transporting layer formed on the charge generating layer and comprising a combination of a butadiene-based amine compound and a hydrazone compound or a combination of a first benzidine compound and a second benzidine compound as a charge transporting material dispersed or dissolved in a binder resin. The amount of the charge transporting material is 5-200 pts.mass based on 100 pts.mass of the binder resin of the charge transporting layer. COPYRIGHT: (C)2006,JPO&NCIPI
