PROBLEM TO BE SOLVED: To execute color shift correction in accordance with execution conditions of color shift correction according to a change in temperature inside an apparatus.SOLUTION: A control part executes color shift correction at a time S1, acquires information T0 on a temperature inside an apparatus during the execution of the color shift correction, and stored the information (S110). The control part subsequently acquires information Tb on a temperature inside the apparatus at a time S2 and stores the information in the storage part (S120), and then acquires information Tn on a temperature inside the apparatus at a time S3 and stores the information in the storage part (S130). When the acquired temperature information Tn is equal to or higher than the temperature information Tb, the control part determines that the temperature inside the apparatus has increased (S140), and when Tn-T0 equals 3°C, executes color shift correction (S150 and S160). Meanwhile, when the acquired temperature information Tn is lower than the temperature information Tb, the control part determines that the temperature inside the apparatus has decreased (S140), and when T0-Tn equals 1°C, executes color shift correction (S160 and S180). |
