Abstract:
An electrophotographic photosensitive member is provided in which black spots on an output image are hardly caused by local charge injection from a support to a photosensitive layer. For this purpose, a conductive layer is formed using a coating liquid for a conductive layer prepared using a solvent, a binder material and a metal oxide particle that satisfies the following relation (i): 45≦A×ρ×D≦65 (i) wherein A denotes the surface area of the metal oxide particle per unit mass [m2/g], D denotes the number average particle diameter of the metal oxide particle [μm], and ρ denotes the density of the metal oxide particle [g/cm3]. The metal oxide particle is a titanium oxide particle coated with tin oxide doped with phosphorus.
