摘要：
The image forming apparatus includes: a log obtaining unit (S1000) configured to obtain a print log which is an execution history of a print job; a color utilization ratio obtaining unit (S1001) configured to obtain a color utilization ratio which is a ratio of chromatic color material utilization when past print jobs were executed from the print log obtained by the log obtaining unit; a determination unit (S1002-S1004) configured to determine to perform mixed color correction and single color correction when the color utilization ratio obtained by the color utilization ratio obtaining unit is equal to or larger than a threshold value and to perform the single color correction without performing the mixed color correction when the color utilization ratio is smaller than the threshold value; and a correction unit (S1007, 801) configured to perform the correction determined by the determination unit.
