An image forming apparatus accepts input of transfer sheet identification information, forms an image on a transfer sheet based on a control value corresponding to the accepted transfer sheet identification information, and accepts input of a correction value of the control value and stores the correction value in correspondence with the transfer sheet identification information in a storage unit. The image is formed on the transfer sheet based on the control value that is corrected by the correction value when the control value is stored in correspondence with the accepted transfer sheet identification information.

Image forming apparatus, printing system and computer-readable storage medium with adjustable image quality

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.
