Abstract
PURPOSE: To reproduce distinct dichromatic copies free from mixed colors by aligning and contacting a latent image holding carrier corresponding to black color and a latent image carrier corresponding to the black color of the opposite polarity therefrom and a specific color, and neutralize the charges corresponding to the black color thereby leaving only the charges corresponding to the specific color.
CONSTITUTION: Reflected light from a dichromatic original 3 having white part 3a, red part 3b and black part 3c is radiated via red filter 6 to a photoreceptor 1 having been charged to-polarity and-charges are left only in the region corresponding to the black part 3c. Next, the reflected light from the original 3 is radiated via cyan color filter 9 to the second photoreceptor 7 having been charged to +, leaving + charges in the regions corresponding to the red and black color parts. Following to this, the surfaces of the first, second photoreceptors are contacted in such a manner that the latent images corresponding to the black color superpose accurately and the charges of the latent images corresponding to the black color are neugralized to leave only the latent image corresponding to the red color of +charge on the second photoreceptor 7. This is then developed with the red toner 10 having been charged to-. Further, this is combined with the developed body having separately reproduced the black color, whereby the dischromatic copy is obtained.
