PROBLEM TO BE SOLVED: To remarkably improve the throughput during double side printing sequence by remarkably shortening the time from a forward rotation of a switch-back conveying or the like in a small power source capacity via stoppage and a reverse rotation to an arrival at stationary reverse rotational speed. SOLUTION: When a motor 31 is driven from a forward rotation to a reverse rotation during a double side printing mode for driving a rotor from the forward rotation to the reverse rotation in the case of executing a predetermined image forming sequence, a limit value of a drive current flowing to the motor 31 is changed within the maximum current value in the cases of the forward drive and the reverse drive of the motor 31. |
