Abstract
PURPOSE: To realize high speed printing in a simple constitution, by forming latent images having different potential depths with respect to each color of recording image in the latent image forming part, and developing by applying bias voltages corresponding to each color of the latent images in the developing sections provided corresponding to each.
CONSTITUTION: The surface of a recording drum D is uniformly charged by a corona charger 1 in a charging part f, and laser beam is radiated to the surface of photoreceptor of the drum D in the latent image forming part a', and latent image corresponding to the character to be recorded is formed. At this time, potential distribution corresponding to the character pattern is formed, and by varying the intensity of laser beam to be radiated depending on the respective color parts by means of modulator 11 and control part 12, the potential depth is varied according to the color parts. By applying bias voltage of sized depending on respective color parts by means of magnetic brushes 13, 14 in developing sections b1, b2, the toner of the color to be developed is deposited on the corresponding color part, and thus multicolor toner image may be formed. Then, the toner image on the drum D is transferred on a transfer paper g conveyed in the transfer part C.
