Abstract
PURPOSE:To obtain the image of high density by making electrostatic latent images corresponding to the data of respective colors formed on 1st and 2nd composite photosensitive bodies visible with toner colored into a data color, transferring the visible images on the same copying paper and fixing it by heat. CONSTITUTION:The data of one color of cyan magenta and yellow is thinned by 50% in terms of area and the data of another color is thinned by 50% to be written in the 1st composite photosensitive body 1A with A-color light and with B-color light respectively, and the data of the rest is thinned by 50% and the data of a black color is not thinned to be written in the 2nd composite photosensitive body 1B with C-color light and with D-color light respectively. Thus, the electrostatic latent images corresponding to the data of the respective colors formed on both composite photosensitive bodies 1A and 1B are made visible with the toner colored into the data color. And the visible images are positioned and transferred on the same transfer sheet and fixed by heat. Now, non-stretching toner is used as the toner Tc, Tm and Tg of the colors such as cyan, magneta and yellow. Thus, the color image of high density can be obtained.
