ABSTRACT:
A method for forming a color image includes a step of spraying three kinds of photoconductive toners with a sensitization wavelength band different from its absorption wavelength band, a step of electrically charging these different toners, a step of exposing these sprayed and electrically charged photoconductive toners to light for selectively removing electrostatic charges, and a step of removing the toners freed of electrostatic charges from the substrate. The magenta color photoconductive toners sensitive to red light, yellow color photoconductive toners sensitive to green light, and the cyan color photoconductive toners sensitive to blue light, are used as aforementioned three kinds of photoconductive colors.
