Multicolor image formation method

Abstract

Abstract PURPOSE: To easily obtain sharp developed colors low in color mixing degree, by specifying the composition of developer and a fixing method. CONSTITUTION: Photoreceptor 1 is illuminated by light through red filter 2a to form a first static latent image, this image is developed with a bisphenol kneaded black toner to form black toner image B, whole receptor 1 containing image B is again charged positively, receptor 1 is illuminated by light through red complementary color filter 2b to form a second static latent image, this image is developed with a crystal violet lactone kneaded red toner to form red toner image R. Both toner images B, R are transferred to recording paper 3 and fixed by heat treatment with halogen lamp 4 or the like, thus permitting heat reaction to be caused in fixing between bisphenol and crystal violet lactone, coloring to violet blue, and this violet blue and red to be synthesized to almost black, and a copied image sharp in tone in the black area to be obtained.
