PROBLEM TO BE SOLVED: To realize a multi-color clear development without causing any irregularity of a color image against the color mixture due to inter-image fogging while achieving the transfer efficiency and transfer quality by slowing down the linear velocity of an image formation is made show as much and realizing a high printing speed (PPM) of a machine. SOLUTION: The inter-latent image time on a photoreceptor from the end of a latent image formable area to the starting end of a next latent formable area for every color is set to be 0.1 to 0.5 seconds. The toner carriers of the respective colors are arranged so that the yellow toner carrier is arranged at the most upstream side and the black toner carrier is arranged at the most downstream side in the rotating direction of the photoreceptor from an exposure position. That is, they are arranged so that the black carrier is arranged at the most upstream side and the yellow carrier is arranged at the most downstream side in the anti-rotating direction of the photoreceptor from a transfer position. |
