Abstract
A charge generating element having an electrically conductive layer, a charge generating layer overlying the electrically conductive layer, and an overcoat overlying the charge generating layer. The overcoat includes dye and a complex of inorganic oxide polymer and a charge carrier. The overcoat has a surface resistivity of from about 1.times.10.sup.10 to about 1.times.10.sup.17 ohms/sq.
