PROBLEM TO BE SOLVED: To form a vivid color image on a transparent film such as an OHP sheet, etc., by reducing an adhesion quantity of, at least, a single-color toner among a plurality color of the toner in a case of selecting the transparent film mode. SOLUTION: An input data is compensated or converted into a γcompensation circuit 4 so as to be prescribed desirable characteristics such as a reflectance linear and a concentration linear. Coat skipping, etc., are performed at the same time. A color compensation/UCR processing circuit 5 is composed of a color compensation processing part which compensates difference between the color separation characteristics of an input system and spectral characteristics of a color material of an output system and calculates the quantity of color materials Y, M, C necessary for faithful reproduction, and an UCR processing device which replaces a part formed by complying three colors Y, M, C with Bk. The OHP copy button on an operation panel is inputted with a key so that the change in a processing constant is executed and processed in the image processing part. In a case of selecting the transparent film mode, the adhesion quantity of, at least, a single toner among respective toners is thus reduced. |
