Abstract

According to the present invention, there is provided a layered-type organic electrophotographic photoreceptor in which a charge generating layer containing organic charge generating material and a charge transporting layer containing organic charge transporting material are constructed on an electroconductive support, characterized in that a value n is not greater than 0.5 in the following equation (1):
η = η₀ En      (1)
where η represents a quantum yield as the whole photoreceptor, E represents an electric field and η₀ represents a constant, and that a film thickness of said charge transporting layer is not less than 30 µm.
