Abstract

PURPOSE: To transfer a black color, two desired colors in complementary relationship, and further multiple colors without any gradation in a simple manner by forming an electrostatic latent image with the use of color filters in complementary relationship and by transferring the latent image additionally to recording paper with the use of colored toners.
