PROBLEM TO BE SOLVED: To provide an image forming apparatus which can suppress the motor over-revolution and fully utilize the lifetime of the components driven by the motor. SOLUTION: A color printer 1 is controlled to select DC motors needed to be newly activated according to a print mode when a print job occurs: determine an activation start time of each selected DC motor by sequentially going back activation times stored in relation to the selected DC motors from an image start reference time; activate one or ones of the DC motors to be activated according to the determined activation start times; measure an actual activation time of the activated DC motor and update a stored content about the activation time based on a measurement result of the actual activation time; and determine an activation start time of each DC motor based on the updated activation time.
