PROBLEM TO BE SOLVED: To prevent reduction in color saturation and deterioration of level difference in gradation, even when the total amount of color materials becomes large.SOLUTION: A total amount calculation unit 20 determines, on the basis of an input color signal comprising a plurality of color components including a black component, the total amount of toner by adding the plurality of color components for every pixel. A color component limiting unit 22, when the total amount of toner becomes equal to or more than a limit value TAC, limits the black component constituting the input color signal together with a plurality of other non-black components (CMYOV), and increasingly limits the black component as the total amount of toner becomes larger. |
