摘要： An electrophotographic light-receiving member comprising a conductive support and provided thereon a photoconductive layer formed of a non-single-crystal material mainly composed of silicon atom and containing hydrogen atom and an element belonging to Group IIIb of the periodic table; wherein the photoconductive layer has hydrogen atom content, an optical band gap and a characteristic energy obtained from the exponential tail of light absorption spectra, all in specific ranges, and has on the surface side thereof a second layer region that absorbs a prescribed amount of light incident on the photoconductive layer and on the support side thereof the other first layer region; the element belonging to Group IIIb of the periodic table being contained in the second layer region in an amount made smaller than that in the first layer region. This can provide an electrophotographic light-receiving member that has achieved all the improvement in chargeability, the improvement in temperature characteristics thereof and the decrease in photomemory, and has been dramatically improved in image quality, and can provide an electrophotographic light-receiving member improved in temperature characteristics of sensitivity and linearity of sensitivity especially in the case where semiconductor lasers or LEDs are used.

摘要： An a-Si photosensitive member and an image forming apparatus are provided which prevent fusion bonding in digital copying machines and attain satisfactory image formation. Specifically, in order that even when uneven abrasion occurs on a drum surface layer, it may not substantially affect the image, a 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 is provided such that the spectral reflectance (%) satisfies the relation of 0≦(Max−Min)/(Max+Min)≦0.20, and a center line average roughness Ra1 of the interface on the surface side of the photoconductive layer and the center line average roughness Ra2 of the outermost surface of the surface layer, within the range of 10 &mgr;m×10 &mgr;m, satisfy the relations of Ra1/Ra2≧1.3 and 22 nm≦Ra1≦100 nm.

摘要： An optical reflection panel made of thermosetting plastic material as a substrate is disclosed. One surface of the substrate is coated with an adherent layer and then an optical reflecting layer is formed on the adherent layer as a reflecting surface for reflecting a light beam. The other surface of the substrate is formed with a reinforcing structure. The reinforcing structure serves to increase the mechanical strength of the optical reflection panel and control the deformation amount. The reinforcing structure includes a number of reinforcing ribs extending along the longitudinal axis of the optical reflection panel and a number of reinforcing ribs perpendicular to the longitudinal axis of the optical reflection panel.
