置。[Claims for Utility Model Registration] Non-magnetic toner is supplied to a rotationally driven toner carrier, the toner is carried on the surface of the carrier and is conveyed, and the latent image carrier and the toner carrier face each other. In the developing device, the electrostatic latent image formed on the latent image carrier is visualized by the toner carried on the toner carrier in a developing region, wherein the toner carrier is a conductive substrate. and a dielectric material formed by transferring a dielectric material in a regular or irregular pattern onto the surface of the substrate, and by charging the dielectric material to a predetermined polarity, the toner can be supported. A charging means is provided which forms a minute closed electric field near the body surface and causes the toner used for visualizing the electrostatic latent image to adhere to the surface of the toner carrier by the closed electric field. developing device.
