Abstract
PURPOSE: To improve image quality of a black image in 2-color electrophotographic copying process, and to enhance sensitivity and stability of the photoreceptor, by laminating specified 2-layer photoconductive layers on a conductive substrate.
CONSTITUTION: First photoconductive layer 2, such as Se, having sensitivity to color A and second photoconductive layer 1 containing a eutectic mixture of an insulating binder resin and a dye transmitting a light of color A and producing carriers by a light of color B are laminated on conductive substrate 3. This photoreceptor is primarily positively charged under uniform illumination of the light of color B by charger 5, and positive charge is absorbed to layer 1 and negative charge is induced in the interlayer between layer 2 and substrate 5. Secondary negative charge is given by charger 6, then white image exposure is effected, and surface voltage of the part of photoreceptor corresponding to original white ground becoms nearly O. In the unexposed area negative surface voltage is retained, and positive surface voltage appears on the area corresponding to color B. Each latent image formed is developed with developers TA and TB each reverse in polarity to each latent image.
