Abstract

A photosensitive layer or a charge generation layer of an electrophotographic photosensitive member (1) contains a gallium phthalocyanine and a particular diamine compound such as 1,2-diaminoethane or 1,3-diaminopropane. The content of the particular diamine compound in the photosensitive layer or the charge generation layer is from 10 ppm to 1,000 ppm (mass ratio) based on the gallium phthalocyanine.
