Abstract
A single-layer photosensitive layer of an electrophotographic photosensitive member contains a charge generating material, a hole transport material, an electron transport material, and a binder resin. The charge generating material is a phthalocyanine pigment. A content percentage of the phthalocyanine pigment relative to the mass of the photosensitive layer is at least 0.70% by mass and no greater than 1.40% by mass. A film thickness of the photosensitive layer is at least 25 μm and no greater than 32 μm. A charge amount difference ΔQ is no greater than 6.50 μC.
