ELECTROPHOTOGRAPHIC PHOTORECEPTOR, PROCESSING CARTRIDGE AND IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor by which a high density and high resolution clear electrophotographic image is stably obtained, by preventing lowering of sharpness due to thinning of letters and lowering of image density due to potential variation of a solid black image region in reversal development, liable to occur in high-speed copying or in a low temperature and low humidity environment, when an electrophotographic image is formed, and to provide a process cartridge using the electrophotographic photoreceptor and an image forming apparatus. SOLUTION: The electrophotographic photoreceptor is used in an image forming apparatus in which a toner image is formed on the electrophotographic photoreceptor at such a process speed as≤110 millisecond travel time (Td) from an imagewise exposing step to a developing step. The electrophotographic photoreceptor includes at least a charge generating layer and a charge transport layer stacked on a conductive support, wherein the charge transport layer contains a compound of formula (1).
