Abstract: A developer and development process for use in an image formation apparatus employing electrophotographic developing technology. In the developer, a reset roll may be positioned around the toner feeding roll so as to come into contact with a toner feeding roll, thus getting the remaining toner from the surface of the toner feeding roll so as to clean the toner feeding roll. A cleaning blade is positioned with its edge coming into contact with the surface of the reset roll, thus removing the remaining toner from the reset roll. The developer almost completely prevents any deterioration of expected operational function of a toner feeding roll even when the developer is used for a lengthy period of time, thereby effectively preventing any reduction in the image quality of processed papers due to such a deterioration of the toner feeding roll's operational function.
