Abstract
An electrophotographic photosensitive member includes, in this order, a support, a charge generating layer having a thickness of more than 200 nm and containing a hydroxygallium phthalocyanine pigment or a chlorogallium phthalocyanine pigment as a charge generating material, and a charge transport layer containing a charge transporting material. The charge generating material satisfies a requirement for a specific parameter.
