ABSTRACT:
An electrophotographic photosensitive member has a support, a charge generation layer containing a charge-generating material and a binder resin, provided on the support, and a hole transport layer containing a hole-transporting material, provided on the charge generation layer. The charge generation layer contains a phenanthrene compound having a structure represented by the following formula (2):wherein Z201and Z202each independently represent an oxygen atom, a ═C(CN)2group or a ═N-Ph group; R201represents a hydrogen atom, a halogen atom, a nitro group, a substituted or unsubstituted alkyl group or a substituted or unsubstituted alkoxy group; and R202represents a halogen-atom-substituted alkyl group.
