Abstract:
1. An electrophotographic photosensitive member which comprises: a conductive support and a photosensitive layer provided on the conductive support, wherein an outermost surface layer of the electrophotographic photosensitive member contains a charge transporting compound having chain polymerizable functional groups, said charge transporting compound represented by the following general formula (9), (10) or (13); the charge transporting compound having been polymerized or cross-linked and cured in the general formula (9), Ar 11 and Ar 12 each represent an aryl group which may have a substituent, which substituent is selected from an alkyl group, an alkoxyl group and an aryl group; Ar 11 and Ar 12 may be the same or different; X 12 represents a divalent alkylene group which may have a substituent, an oxygen atom or —O-Z 12 - (Z 12 is a divalent alkylene group); b is an integer of 0 or 1; R wherein, X 11 represents a divalent organic residual group which may have a substituent, which substituent is selected from an alkyl group, an aralkyl group, an aryl group and a halogen atom; a represents an integer of 0 or 1; and P 11 represents any one of the chain polymerizable functional groups represented by the following general formulas (2) to (6); in the general formula (10), Ar wherein R 24 and R 25 each represent an alkyl group which may have a substituent, an aralkyl group which may have a substituent, an aryl group which may have a substituent, or a hydrogen atom, and R 24 and R 25 may be the same or different; and the substituents are each selected from an alkyl group, an aralkyl group, an aryl group and a halogen atom wherein X 21 represents a divalent organic residual group which may have a substituent, which substituent is selected from an alkyl group, an aralkyl group, an aryl group and a halogen atom; a represents an integer of 0 or 1; and P 21 represents any one of the chain polymerizable functional groups represented by the following general formulas (2) to (6); in the general formula (13), Ar n represents an integer of 0 or 1; X
