ABSTRACT:
An electrophotographic photoconductor which comprises an electroconductive support; an undercoat layer formed thereon comprising (i) a reaction product between an active-hydrogen-containing compound having a plurality of active hydrogens and an isocyanate-group-containing compound, which reaction product serves as a binder resin, and (ii) finely-divided particles of indium oxide dispersed in the reaction product; and a photo-sensitive layer formed on the undercoat layer. The indium oxide may be partly replaced by metal oxide, metal fluoride, metal nitride, metal carbide or metal boride in an amount of not more than 50 wt. %.
