Electrophotographic photosensitive member, process cartridge, and electrophotographic apparatus

A process cartridge comprising:

• an electrophotographic photosensitive member;
• and
• at least one means selected from the group consisting of a charging means, a developing means, a transfer means and a cleaning means, which are integrally supported, the process cartridge being detachably mountable to the main body of an electrophotographic apparatus,
• said electrophotographic photosensitive member being an electrophotographic photosensitive member comprising:
• a support;
• and,
• 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,
• wherein said charge generation layer contains a phenanthroline compound having a structure represented by the following formula (3):
• wherein Z301 and Z302 each independently represent an oxygen atom, a ═C(CN)2 group or a ═N-Ph group;
• and R301 and R302 each independently represent a hydrogen atom, a halogen atom, a nitro group, a substituted or unsubstituted alkyl group or a substituted or unsubstituted alkoxy group.
