An electrophotographic photoconductor, including an electrically conductive substrate, an undercoat layer containing a filler and a binder resin and provided on the substrate, and a photoconductive layer provided on the undercoat layer and containing a binder resin. At least one compound selected from crown ethers, polyalkyleneglycol ethers, polyethyleneglycol monocarboxylic acid esters, polyethyleneglycol dicarboxylic acid esters, and hydroxy-terminated random or block copolymers containing oxypropylene and oxyethylene groups is incorporated into (a) the undercoat layer or (b) into a charge generating layer of the photoconductive layer. In the case of (a), the photoconductive layer is a dried coating of a composition containing at least one solvent selected from cyclic ethers, ketones and aromatic hydrocarbons.
