ELECTROPHOTOGRAPHIC PHOTOSENSITIVE MEMBER, METHOD FOR PRODUCING THE SAME, ELECTROPHOTOGRAPHIC APPARATUS AND PROCESS CARTRIDGE, AND CHLOROGALLIUM PHTHALOCYANINE CRYSTAL

摘要

PROBLEM TO BE SOLVED: To provide an electrophotographic photosensitive member that suppresses a ghost memory, a method for producing the electrophotographic photosensitive member, an electrophotographic apparatus and a process cartridge, and a chlorogallium phthalocyanine crystal.SOLUTION: A photosensitive layer of an electrophotographic photosensitive member contains a particular chlorogallium phthalocyanine crystal in which an organic compound is contained. The organic compound has a Hansen solubility parameter δtotal of 24.0 or more and 35.0 or less, a polar term δP of 13.5 or more and 21.0 or less, and a dispersion term δD of 15.0 or more and 19.5 or less.
