ABSTRACT:
A color image forming method by superimposing plural kinds of toner with different colors on a surface of a photoreceptor body is disclosed. The surface of the photoreceptor is uniformly pre-charged with electricity. A kind of toner is selected according to a predetermined order. A latent image corresponding to the selected toner, and consequently corresponding to a selected color, is formed on the surface by a photo-electric exposure. A toner image is formed by developing the latent image with the selected toner. A multiple color image is formed by repeating the above two steps with regard to succeeding colors and kinds of toners until all kinds of toner having been developed. In repeating the development, the following formulas are satisfied under the supposition that (Q/M)n is an amount of electrification of toner used in the n-th development.
