摘要:
An image forming apparatus is disclosed that includes an image carrier, a driving source, a rotation detection unit, and a control unit that performs fluctuation pattern recognition processing, control pattern construction processing, speed fine-adjustment processing, and remaining pattern recognition processing. The control unit is configured to perform control pattern correction processing for setting a frequency band of a remaining speed fluctuation to be detected by the remaining pattern recognition processing narrower than a frequency band of a speed fluctuation to be detected by the fluctuation pattern recognition processing and correcting the speed control pattern so as to be a pattern capable of reducing even the remaining speed fluctuation based on a remaining speed fluctuation pattern recognized by the remaining pattern recognition processing.
