PROBLEM TO BE SOLVED: To suppress color unevenness when a toner image different in hue and high in luminosity is transferred from an intermediate transferring body to a recording medium even when the toner image is transferred with the toner image overlapped on a toner image transferred to the intermediate transferring body.SOLUTION: An image formation device includes an image formation unit 12 that is composed of: a downstream side image formation unit 13 in which a plurality of toner image formation units 20 is arranged so that luminosity of toner is lower as the plurality of toner image formation units heads for a downstream side; and an upstream side image formation unit 15 in which one toner image formation units 20 different in hue from toner owned by the toner image formation units 20 of the downstream side image formation unit 13 and having the toner of the lower luminosity than the toner of the highest luminosity of the downstream side image formation unit 13 is arranged or plurally arranged on an upstream side of the downstream side image formation unit 13. Let a volume average particle diameter of the toner of the toner image formation unit 20 of the upstream side image formation unit 15 be Dt, and the largest volume average particle diameter of the toner of the toner image formation units 20 of the downstream side image formation unit 13 be Dmax, the image formation device is set to Dt>Dmax.SELECTED DRAWING: Figure 1 |
