1. An electrophotographic photosensitive member comprising:
a support, an undercoat layer formed on the support, a charge generation layer formed on the undercoat layer and comprising a charge generating material, and a hole transport layer formed on the charge generation layer and comprising a hole transporting material, wherein the undercoat layer comprises an amine compound represented by the following formula (1): where, in the formula (1), R1 to R10 each independently represent a hydrogen atom, a halogen atom, a hydroxy group, a carboxyl group, an alkoxycarbonyl group, an aryloxycarbonyl group, a substituted or unsubstituted acyl group, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted aryloxy group, or a substituted or unsubstituted amino group, provided that at least one of R1 to R10 represents an amino group substituted with a substituted or unsubstituted aryl group, or an amino group substituted with a substituted or unsubstituted alkyl group; and X1 represents a carbonyl group or a dicarbonyl group. |
