ELECTROPHOTOGRAPHIC PHOTORECEPTOR AND IMAGE FORMING APPARATUS INCLUDING THE SAME

摘要

An electrophotographic photoreceptor that excels in not only electrical properties, such as sensitivity and photoresponse properties, but also abrasion resistance duration and that can prevent formation of flaw and density unevenness in formed images over a prolonged period of time. In particular, there is provided electrophotographic photoreceptor (1) comprising charge transport layer (6) wherein an enamine compound of the following general formula (1), for example, an enamine compound of the following structural formula (1-1) is contained, which electrophotographic photoreceptor (1) exhibits a creep value (CIT), measured in an environment of 50% relative humidity at 25°C with an indentation maximum load of 30 mN applied onto the surface for 5 sec, of 2.70 to 5.00% and at its surface exhibits a value of hardness against plastic deformation (Hplast) of 220 to 275 N/mm<2>.
