PURPOSE:To take a polychromatic copy with one original without forming originals corresponding to respective development colors by specifying a color for every area section of the original, and forming an electrostatic latent image of only areas corresponding to each development color through the 2nd exposing means. CONSTITUTION:Areas of the original are inputted successively with an input pen 22 and a color is specified for every area with a color specifying button 31; and the original is placed on an original platen and an electrostatic latent image is formed on a photosensitive body. When an original area I is developed on the photosensitive body in the 1st color, a means 20 is turned on over its entire entire surface to erase a latent image as shown by hatching until the area I reaches the 2nd exposing means 20, the lateral width corresponding part is turned on when the area I passes through the means 20, and then the means is turned off entirely to leave the latent image only in the area I eventually. Other color section are passed through the same process to develope the image in three colors by the three developing devices. Therefore, a polychromatic copy is taken with only one original without forming originals corresponding to respective development colors. |
