PURPOSE:To reduce the size and cost of a device by forming repeatedly an electrostatic image by the same device to an image forming body having a photoconductive sensitive layer and repeating formation and development of the electrostatic image thereby obtaining the color image. CONSTITUTION:The surface of an image forming body 1 which is destaticized by a destaticizer 13 and is cleaned by a cleaning device 14 is subjected to the 1st electrostatic charge by a charger 2 and the charged surface is subjected to the 1st image exposure by image exposure 4 by each color. The resulting electrostatic image is subjected to the 1st development by a developing device using a developer of the color toner corresponding to the image exposure 4 among developing devices 5-8. After the surface is destaticized by the destaticizer 13, the 2nd electostatic charge is executed again by the charger 2 at the 2nd turn and the charged surface is subjected to the 2nd image exposure by the image exposure 4 of the color different from the color of the first exposure. The image is developed for the second time by the developing device of the corresponding color toner. The 3rd and 4th formation and development of the electrostatic image are thereafter repeated in the same way. |
