<P>PROBLEM TO BE SOLVED: To provide an image forming device that corrects imaging conditions of imaging means based on a colorimetric result of an output multi-color toner image and can achieve more stabilized colors of an output image by performing correction with excellent accuracy. <P>SOLUTION: A copying machine 600 superimposes primary color toner images formed by a latent image writing unit 21 being imaging means and four image forming units 18 on an intermediate transfer belt 10 so as to form a multi-color toner image and transfers the multi-color toner image on a recording paper P. A main controller that is image information color separation means estimates individual output halftone dot ratio estimated values of the primary color toner images constituting the multi-color toner image based on a spectral reflectance distribution of the multi-color toner image obtained by a line spectrometer 900 on the recording paper P, and corrects imaging conditions of the primary color toner images based on a comparison result between individual output halftone dot ratio estimated values of primary colors having been estimated and control halftone dot ratios of the primary colors. <P>COPYRIGHT: (C)2012,JPO&INPIT |
