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.
