Surface-potential-decrease phenomenon occasionally occurs by the interaction between the development roller and the photoreceptor via toner in the non-magnetic mono-component impression development process. The surface-potential-decrease phenomenon was investigated by using polymerized styrene-acrylic resin and pulverized polyester toners. The surface-potential-decrease is much larger with the styrene-acrylic resin toner than the polyester resin toner. The surface-potential-decrease phenomenon may be originated from two causes, one is the tribocharging between toner and photoreceptor, and the other is the charge injection to the photoreceptor through the toner. The order in the triboelectric series between photoreceptor and toner resin is most important. It is preferable for the reduction of the surface-potential-decrease phenomenon and the stability of development process that the toner resin is neutral to the photoreceptor in the order of the triboelectric series.
