Electrophotographic photosensitive member, process cartridge, and electrophotographic apparatus
摘要:
A conductive layer of an electrophotographic photosensitive member contains a first metal oxide particle, a second metal oxide particle, and a binder material. The first metal oxide particle is a zinc oxide particle or tin oxide particle coated with tin oxide doped with phosphorus, tungsten, fluorine, niobium, or tantalum, and the second metal oxide particle is a tin oxide particle doped with an element selected from the group consisting of phosphorus, tungsten, fluorine, niobium, and tantalum, the element being the same as the element with which the tin oxide of the first metal oxide particle is doped. The conductive layer satisfies formulae (1) and (2) 2≦{(V2/VT)/(V1/VT)}×100≦25  formulae (1): 15≦{(V1/VT)+(V2/VT)}×100≦45  formulae (2).
