Abstract
PURPOSE: To obtain a copy image of high resolution, by transferring the latent image once formed in the photoreceptor onto the surface of the photoreceptor.
CONSTITUTION: A laminated photoreceptor P consisting of a first photoconductive layer 2 chargeable in both positive and negative polarity and having sensitivity to blue and red color lights, and a second photoconductive layer 3 chargeable in negative polarity and having sensitivity to green color light is uniformly exposed on a conductive substrate 1 by means of a lamp 5 equipped with a red color filter 4 while it is primarily charged uniformly in negative polarity by means of a corona discharger 6. After secondary charging uniformly in positive polarity in the darkness by means of a corona discharger 7, the optical image of the original 8 possessing black color part 8a, white color ground part 8b and red color part 8c is radiated, and a red color toner 9 is supplied then to reproduce the red color part 8c. Uniformly charging in the same polarity as the latent image corresponding to the red color in the darkness by means of a corona discharger 10, the latent image corresponding to black color formed on the first photoconductive layer 2 is transferred onto the surface of the photoreceptor, and is exposed through the red color filter 11, then a black color toner 12 is supplied. As a result, an image clear in both red and black colors may be obtained.
