Abstract
The present invention provides photoconductive paints which have excellent dispersability and dispersion stability and which allow formation of coatings with high coating strength and excellent smoothness. The invention relates to photoconductive paint composed primarily of an inorganic photoconductive material and a binding resin formed on a conductive substrate, wherein the binding resin contains compound fine particles (A) and a resin (B) as defined below, in a solid weight ratio of compound fine particles (A)/resin (B) in the range of 0.5/9.5-4.0/6.0. The compound fine particles (A) have an organic polymer bound to surfaces of inorganic fine particles, and the resin (B) is a resin composition obtained by polymerizing an acrylic monomer mixture, the resin having an acid value of 2.0-12.0.
