Abstract

The image reproducing machine disclosed in Figure 1 represents a high-speed color image reproducing machine. The machie comprises a vertically extended belt-type photo-receptor 1 extended among several supporting rollers 2, a charging station 3, a plurality of Raster Outputting Scanners (ROS) 4, 5, 6, 7, a plurality of developing apparatus 8, 9, 10, 11, an image transfer station 12 to transfer a developed image formed on the photo-receptor 1, a cleaning station 13 and a paper transporting path 14. Each ROS and developing apparatus corresponds to each reproduced color, (for example, yellow, cyan,

magenta, black). The photoreceptor is first charged at the charging station 3, then, for example, an electrostatic image of yellow color is formed by ROS 4, then developed with yellow toner by the developing device 8. Thus, the yellow toner image is formed on the photoreceptor 1. The surface of the photoreceptor is optionally re-charged by re-charging device 20, then, as similar to the former yellow image forming process, a magenta toner image is formed onto the surface of the photoreceptor by using ROS 5 and the developing apparatus 9. Similar to the former process, by using charger 21, 22, ROS 6, 7, the developing apparatus 10, 11, a full-color toner image including cyan and black color toner image is formed onto the surface of the photoreceptor. The color toner image is then transferred onto a sheet of copy paper (...
