ABSTRACT:
A printer according to this invention comprises a latent image supporter having an endless belt shape and provided with separate image-forming regions, and a developing unit capable of independently supplying toners of different colors onto latent images formed on the latent image supporter. With the above arrangement, latent images for different colors are formed in the respective image-forming regions of the latent image supporter. Toners of the individual colors are then supplied to the respective latent images, thereby forming toner images of the respective colors. The toner images are transferred onto a sheet to provide an intended color mixing, and are then fixed by a fixing unit. The charges and toners remaining on the surface of the latent image supporter are removed by a static eliminator and a cleaner, respectively, so that the belt becomes ready for the next printing cycle.
