PROBLEM TO BE SOLVED: To suppress an influence of a thermochromism phenomenon in which colors in an image for measurement change according to temperature, so as to accurately measure the colors in the image for measurement.SOLUTION: An image forming apparatus 100 includes a color sensor 200 that measures colors in a patch image fixed on a sheet 110 by a fixing unit. The color sensor 200 converts a measurement result into a measurement result in a room-temperature environment on the basis of a conversion table (Fig. 8). A printer controller 103 causes the color sensor 200 to repeatedly measure the patch image fixed by the fixing unit to create the conversion table (Fig. 8). |
