Electrophotographic photosensitive member, process cartridge and electrophotographic apparatus, and gallium phthalocyanine crystal

Abstract

An electrophotographic photosensitive member is provided. The electrophotographic photosensitive member can output an image having few image defects due to a ghost phenomenon not only under a normal temperature and normal humidity environment but also even under a low temperature and low humidity environment, which is particularly a strict condition. A process cartridge and an electrophotographic apparatus having the electrophotographic photosensitive member are also provided. The electrophotographic photosensitive member has a support and a photosensitive layer formed on the support, wherein the photosensitive layer includes a gallium phthalocyanine crystal including a compound having a structure in which a 7-membered ring and a 5-membered ring are condensed to each other within the crystal.
