We have studied the photogeneration and charge carrier transport processes in relation to the molecular structures of materials used in photoreceptors to elucidate the mechanisms of these phenomena. We applied the results to the design of photoconductive materials for improvement of performance and developed highly sensitive unsymmetrical azo pigments and new charge carrier transport materials with high mobility.
