Abstract:
Provided is an electrophotographic photosensitive member, a process cartridge and an electrophotographic apparatus each having the electrophotographic photosensitive member that can output an image having less image defects due to a ghost phenomenon not only under a normal-temperature, normal-humidity environment but also under a low-temperature, low-humidity environment as a particularly severe condition. The electrophotographic photosensitive member includes a support and a photosensitive layer formed on the support, in which the photosensitive layer includes a gallium phthalocyanine crystal containing a specific amine compound in itself.
