Abstract
A color printer of the invention 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. An image forming apparatus capable of preventing the motors from rotating more than necessary and effectively utilizing the life of components to be driven by the motors can be provided.
