Abstract (en)
[origin: EP0340523A2] 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): eta = eta 0 E<n> (1) where eta represents a quantum yield as the whole photoreceptor, E represents an electric field and eta 0 represents a constant, and that a film thickness of said charge transporting layer is not less than 30 mu m.
