Abstract:
An electrophotographic photosensitive member formed by successively stacking on a conductive substrate a photoconductive layer comprising amorphous Si and a surface protective layer comprised of an amorphous material, wherein the minimum value (Min) and the maximum value (Max) of the reflectance (%) of the photosensitive member within the wavelength range of 600 nm to 700 nm satisfy the relation of 0&lE;(Maxâˆ’Min)/(Max+Min)&lE;0.20, and a center line average roughness Ra1 of an interface on the surface side of the photoconductive layer and a center line average roughness Ra2 of the outermost surface of the surface protective layer, within the range of 10 &mgr;mÃ—10 &mgr;m, satisfy the relations of Ra1/Ra2&gE;1.3 and 22 nm&lE;Ra1&lE;100 nm.
