Abstract
PURPOSE: To obtain the distinct copies by so constituting the apparatus that the electrostatic latent images of only the respective chromatic colors in correspondence to the chromatic colors of the original picture are formed and that they do not superpose with the electrostatic latent images of the other colors.
CONSTITUTION: A photosensitive body 1 is subjected to primary charging by a charger 2. When it is exposed with the original picture 3 through a red filter 4, only the black part corresponding positions (b) of the original picture 3 become of a high potential, thereby forming a negative electrostatic latent image (a) for red color. This negative electrostatic latent image (a) is developed with black toner 5. Next, this photosensitive body 1 is destaticized by a destaticizing lamp or the like and again it is charged with a secondary charge charger 8. When the toner 5 is removed with a cleaner 9, the black part corresponding parts (b) form an electrostatic latent image (n). When the original 3 is again exposed so as to optically align and superpose to and on the negative electrostatic latent image (a) this time through a cyan filter 10, then the electrostatic latent image in which only the red part corresponding part (r) are of a high potential is formed. After this it is developed and transferred by red toner 11 to complete copying of the red color. In this way, the distinct copy may be obtained.
