    • Electrophotographic light-sensitive elements according to the invention comprise(a) a conductive support;(b) a photoconductive layer; and(c) a surface protective layer.The conductive support is formed in a sheet-like or cylindrical shape from any suitable conductive material, and acts as an electrode of the light-sensitive element as well as acting as a physical support. The photoconductive layer comprises amorphous hydrogenated silicon having a high absorption efficiency and photoconductivity. The a--Si:H of a photoconductive layer may contain other elements such as fluorine, carbon, nitrogen and germanium, and may be doped with elements belonging to groups III and V of the periodic table. The surface protective layer is the outermost layer of an electrophotographic light-sensitive element according to the invention, and imparts resistance to environmental conditions. The surface protective layer comprises hydrogenated amorphous carbon, and may additionally contain silicon, nitrogen, oxygen or fluorine. The percentage of hydrogen can vary from 1 to 60 mole percent depending upon the conditions under which the surface layer is formed. Preferably, hydrogen is between 10 and 40 mole percent.

    • A photoconductor for electrophotography includes a conductive substrate and an organic undercoating layer on the conductive substrate. An organic charge generation layer is deposited on the undercoating layer, and an organic charge transport layer is deposited on the charge generation layer. The undercoating layer contains soluble polyamide resin and/or normal-butylated melamine resin as its main components. Alternately, the undercoating layer may contain resin as its main component, into which are dispersed small particles of anatase-type titanium dioxide. The surfaces of the anatase-type titanium dioxide particles may be treated with aminosilane. These undercoating layers produce a laminate-type photoconductor, which exhibits excellent electrophotographic characteristics that are stable during repeated use over long periods of time, and which vary little in a high temperature and high humidity atmosphere, as well as in a low temperature and low humidity atmosphere.
