Abstract
An electrophotographic photoconductor include an conductive substrate; an undercoat layer provided on the conductive substrate; and a photosensitive layer having charge-generation and charge-transport functions provided on the undercoat layer. The undercoat layer includes a polyamide resin and methylhydrogenpolysiloxane-treated titanium dioxide and preferably styrene-maleic acid half-ester copolymer. The photoconductor can be produced by the steps of: dispersing a polyamide resin and methylhydrogenpolysiloxane-treated titanium dioxide and preferably styrene-maleic acid half-ester copolymer in a mixture solvent of an alcohol-type solvent and a halogenated hydrocarbon-type solvent, thereby preparing a coating liquid for an undercoat layer; applying the coating liquid onto a conductive substrate, thereby providing an undercoat layer on the substrate; and forming a photosensitive layer on the undercoat layer.
