Demands to life improvement of organic photoreceptor enhance in the electrophotograph system, therefore research and development are further done actively. In particular electrostatic property performance and the latent image reproduction performance that are high stability of organic photoreceptor are big subjects in the development of a long life organic photoreceptor. We suggest optimization of system design, and the layer composition of organic photoreceptor, and the protection layer to contain fine particles (FRL), and the new hole transport materials which have acid scavenge function (AS donor) for these subjects. By this report, we introduce life improvement technologies of organic photoreceptor in Ricoh.
