Abstract
An electrophotographic photosensitive member which has VA, VB, and d satisfying an expression (|−600−VA|−|−600−VB|)/d=0.13 and VC satisfying an expression −5=−(−450−VC)=2 provides an excellent suppressing effect on ghost images and hardly causes a ghost phenomenon even when it is mounted on a color electrophotographic apparatus or an electrophotographic apparatus having no electrostatic removal device. The invention also relates to a process cartridge and an electrophotographic apparatus each having such an electrophotographic photosensitive member.
