Abstract
The image forming apparatus includes an image forming section that forms a patch image T on a recording material P, a fixing unit that fixes the patch image, a spectral color measurement device that irradiates light onto the patch image T that was fixed by the fixing unit, and measures reflected light from the patch image, a white reference plate disposed facing the spectral color measurement device; and a control unit that controls a density or a chromaticity of an image based on a result obtained by measuring the patch image and a result obtained by measuring the white reference plate by means of the spectral color measurement device. It is thereby possible to improve the color measurement accuracy of a color measurement device.
