PURPOSE:To eliminate an exposing and forming process and to miniaturize the title device by impressing a prescribed voltage between conductive powder and plural electrode heads, pouring electric charges into the conductive powder from a member supporting said powder and forming an image on an image forming member. CONSTITUTION:Rollers 6 and 6' keep the surface potential of the image forming member 5 constant to prevent base fogging. The electrode head 8 is structured to arrange plural divided electrodes 81 on an insulating substrate 80 in a strip and all parts other than a part coming into contact with the image forming member 5 are insulated by an insulating layer 82, and driven by a driver IC 83. To form an image on the image forming member 5, a negative voltage is impressed on each electrode with respect to the conductive powder 1, and when no image is formed, each electrode is brought into the same potential as that of the conductive powder 1. Then, the image forming member 5 and the image forming member 10 are overlapped correctly and passed by a fixing device 9 as they are, thereby transferring an image onto the image forming member 10. In such a way, the exposing and forming process is eliminated to miniaturize the device. |
