摘要： PROBLEM TO BE SOLVED: To inexpensively, stably and precisely reproduce colors.SOLUTION: An image forming apparatus 1 stores a reference colorimetric value of reference color patches of a plurality of colors, a reference RGB value with which an acquisition section 30 acquires the reference color patches, and a first linear conversion matrix for converting the reference RGB value into the reference colorimetric value in a non-volatile memory. The image forming apparatus 1 images a colorimetry adjusting color patch CP recorded in a recording medium P by a recording head 20 by the acquisition section 30, converts the RGB value into an imaged colorimetric value, selects the prescribed number of reference color patches whose distance from the reference color patch is close to that of the imaged colorimetric value, and selects the RGB value of the colorimetry adjusting color patch CP acquired by the acquisition section 30, which corresponds to the selected reference color patch, as a selection RGB value. The image forming apparatus 1 calculates a second linear conversion matrix for converting the selection RGB value into the colorimetric value of the reference color patch and converts the RGB value of the colorimetric adjusting color pach CP acquired by the acquisition section 30, into a Lab colorimetric value by using the second linear conversion matrix.
