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, 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 phenanthrene compound having a structure represented by the following formula (2)
• wherein Z201 and Z202 each independently represent an oxygen atom, a ═C(CN)2 group or a ═N-Ph group;
• R201 represents a hydrogen atom, a halogen atom, a nitro group, a substituted or unsubstituted alkyl group or a substituted or unsubstituted alkoxy group;
• and R202 represents a halogen-atom-substituted alkyl group.
