An electrophotographic photosensitive member, a process cartridge and an electrophotographic apparatus are provided which not only secure mechanical strength sufficiently but also bring a vast improvement in charge transport performance and which can well satisfy electrical properties. An electrophotographic photosensitive member is provided an outermost surface layer of which contains at least a charge transporting compound having chain polymerizable functional groups which is represented by the following general formula (1-1) or (1-2); the charge transporting compound having been polymerized or cross-linked and cured. Also provided are a process cartridge and an electrophotographic apparatus which have such a photosensitive member. 

Electrophotographic photosensitive member, process cartridge, and electrophotographic apparatus

An electrophotographic apparatus comprises an electrophotographic photosensitive member, and a charging assembly, an exposure assembly, a development assembly, an image-transfer assembly, and a cleaning assembly arranged around the photosensitive member in this order, wherein the photosensitive member has a surface layer containing fluoroplastic particles; and the electrophotographic apparatus further comprises a polishing assembly for polishing the surface of the photosensitive member after the transfer assembly and before the cleaning assembly.
