Abstract
An electrophotographic photosensitive member includes a support member, a charge generating layer containing a phthalocyanine pigment as a charge generating material, a charge transport layer containing a charge transporting material in this order. The charge generating layer has a thickness of less than 200 nm, and the phthalocyanine pigment includes phthalocyanine crystalline particles having a particle size distribution and satisfies a requirement that the volume average of the products of Φi and Ψi is 0.31 or more.
