The photoconductive properties of the pigments containing anthraquinone are studied in bilayer photoreceptor. A linear relationship between pigments that bear a substituent in the anilide ring in the coupler moiety and Hammett constant σ was obtained. Therefor, we conclude that electron-withdrawing groups enhances the sensitivity of these pigments.
