PROBLEM TO BE SOLVED: To obtain a small-sized image forming device which does not cause the lowering of performance and the deterioration of an image due to a product of electric discharge, does not generate a positive residual image due to a residual toner after transfer and adopts a cleaner-less process. SOLUTION: An image forming device is simplified by allowing a developing means 4 to act also as a cleaning means which recovers a residual toner after transfer. A product of electric discharge is efficiently recovered by disposing a photocatalytic material 10 around a discharge region in the image forming device. An additive added developer is used so as to enhance transfer efficiency and to suppress the generation of a positive residual image. |
