PROBLEM TO BE SOLVED: To reduce the scale and the cost of a driving circuit by controlling respective correction means so that they are switched to be individually driven or simultaneously driven based on calculated correction amount. SOLUTION: A calculation means (registration controller) 620 calculates the correction amount for correcting the deviation of an image formed on a recording medium in accordance with plural detected results concerning plural image forming means. A control means (registration controller) 620 switches and controls respective mirror motors 323 to 326 through one mirror motor driver 622 based on the calculated correction amount between 1st driving where the motors 323 to 326 are individually driven to correct a positional deviation element and 2nd driving where the motors 323 to 326 are simultaneously driven to prepare for the 1st driving. Therefore, simultaneous driving for confirming the operation of the motors 323 and 326 and individual driving for original registration correction are freely switched and executed by one driving control system. |
