    • The electrophotographic photoreceptor according to the present invention has a conductive support (10) and a photoconductive layer laminated on the conductive support. The conductive layer is characterized by making a quantity of reflected lights with respect to exposure of a coherent light as a light source to be small and by having a short wavelength surface roughness in order to suppress a quantity of interference lights produced by the reflected lights and reflected lights from or incident lights on the photoconductive layer. Specifically, the conductive support (10) has aluminum or aluminum based alloy, and the maximum height (Ry) of the surface roughness of the conductive support is 0.8 &mgr;m or more and 2.0 &mgr;m or less. Further, the reflectivity of the light on the surface of the conductive support is equal to or less than 35% of a quantity of exposure light of a light source of a coherent light. This is able to prevent generation of the interference fringes. The surface of the conductive support is preferably processed for an anodic oxidation film. In this case, the surface roughness subjected to the anode oxidation treatment has a roughness waveform composed of two components shown in the following equation: 1.0a≦b≦=2.5a, wherein, a is the roughness of the short waveform (fine roughness) component, and b is the roughness of the long waveform (coarse roughness) component.

    • In a photoconductive element comprising a conductive support, e.g., an electrically conductive film, drum or belt on which a negatively chargeable photoconductive layer is formed, an electrical barrier layer is formed between the support and the photoconductive layer. The barrier layer provides a high energy barrier to the injection of positive charges but transports electrons under an applied electric field. The barrier layer of the invention transports charge by electronic rather than ionic mechanisms and, therefore, is not substantially affected by humidity changes. The barrier layer comprises a polyester-co-imide, polyesterionomer-co-imide or polyamide-co-imide having covalently bonded as repeating units in the polymer chain, aromatic tetracarboxylbisimide groups of the formula: wherein Ar1 and Ar2 represent, respectively, tetravalent and trivalent aromatic groups of 6 to 20 carbon atoms.
