To achieve reproduction of a target hue and suppression in decrease in saturation by suppressing the amount of toner used for development in printing on a form having large surface unevenness.

There is provided an image formation device which forms an image on a recording medium using a plurality of color materials, the image formation device including acquisition means of acquiring surface roughness precision indicating an index representing roughness of a recording surface of the recording medium, and control means of controlling an increment in the amount of a coloring material, formed on an outermost surface of the recording surface among the plurality of color materials, based upon the amount of the color material on the recording medium whose recording surface has roughness less than roughness that the surface roughness information indicates to an amount larger than increments of other color materials among the plurality of color materials.
