Provided is a method of producing an electrophotographic photosensitive member having improved sensitivity and capable of outputting 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 method of producing a gallium phthalocyanine crystal includes subjecting a gallium phthalocyanine and a specific amine compound, which are added to a solvent, to a milling treatment to perform crystal transformation of the gallium phthalocyanine. In addition, the gallium phthalocyanine crystal is used in the photosensitive layer of the electrophotographic photosensitive member.

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.
