Abstract
PURPOSE: To obtain a dichromatic image by laminating the first photoconductive layer and the second photocondutive layer on an electrically conductive substrate in order and adding a coloring agent, to the second layer, which cuts a specified wavelength region of the sensitive wavelength region of the first layer and controls the sensitivity of the second layer.
CONSTITUTION: On electrically conductive substrate 11 the first photoconductive layer 12 made of photosemiconductor having sensitivity all over the visible light region is formed, and on layer 12 the second photoconductive layer 14 having sensitivity to red light and absorbing red light is formed to manufacture receptor 1 in which the red sensitivity of layer 12 has been canceled off. By subjecting receptor 1 to primary charging the surface of layer 14 is negatively charged, and layer 12 is positively charged. After uniformly exposing receptor 1 to red light charging of the reverse polarity to the primary charging is carried out, and black BL-white W-red R original 2 is exposed. Layers 12, 14 are charged positively and negatively and developed with black toner Tb and red toner Ta of reverse polarities. Thus, by a single exposure of original 2 a black-red-white dichromatic image is obtained.
