An electrophotographic photoreceptor includes, on a conductive support, a laminated photosensitive layer in which a charge generating layer containing a charge generating material and a charge transporting layer containing a hole transporting material are laminated in this order, or the laminated photosensitive layer and a surface protecting layer laminated on the laminated photosensitive layer, wherein an outermost surface layer of the electrophotographic photoreceptor contains an electron transporting material having a maximum absorption at a wavelength of equal to or less than 500 nm in a spectral absorption spectrum and a silica particle, a mass ratio of the silica particle to the electron transporting material is 1.0 to 5.0, and an impedance change rate of the electrophotographic photoreceptor when a frequency is changed from 4 Hz to 50 Hz is 96% to 91%.
