ELECTROPHOTOGRAPHIC PHOTOSENSITIVE MEMBER, METHOD FOR PRODUCING ELECTROPHOTOGRAPHIC PHOTOSENSITIVE MEMBER, PROCESS CARTRIDGE AND ELECTROPHOTOGRAPHIC APPARATUS, AND HYDROXYGALLIUM PHTHALOCYANINE CRYSTAL

摘要

PROBLEM TO BE SOLVED: To provide an electrophotographic photosensitive member in which sensitivity unevenness caused by thickness unevenness is suppressed.SOLUTION: An electrophotographic photosensitive member includes a support and a photosensitive layer formed on the support, and the photosensitive layer contains a hydroxygallium phthalocyanine crystal having peaks at Bragg angles 2&thetas;±0.2° of 6.9°, 7.7°, 16.4°, 24.4° and 26.5° in CuKα X-ray diffraction.
