Patent ID: 8503028

Claim:
An image forming apparatus comprising: a printing unit configured to print an image on a recording medium in accordance with a print job, wherein the printing unit performs a high-speed double-sided print processing operation to print an image on a second recording medium during a period between when a first side of a first recording medium is printed and when a second side of the first recording medium is printed when a plurality of recording media are being subjected to double-sided printing, wherein the print job includes a plurality of high-speed double-sided print processing operations including the high-speed double-sided print processing operation; a processing unit; memory having executable instructions stored thereon that, when executed by the processing unit, cause the image forming apparatus to function as: an accepting unit, which accepts the print job; an adjustment unit, which performs an image quality adjustment to adjust image quality achieved during printing; a determination unit that determines whether or not adjustment execution conditions will be fulfilled during performance of the high-speed double-sided print processing operation before the high-speed double-sided print processing operation is initiated; and a control unit, which controls the adjustment unit to perform the image quality adjustment before initiation of the high-speed double-sided print processing operation, which was determined would fulfill the adjustment execution conditions, when the determination unit determines that the adjustment execution conditions will be fulfilled, wherein the control unit controls the adjustment unit to perform the image quality adjustment during a period between sequentially adjacent high-speed double-sided print processing operations when repeatedly subjecting a given number of recording media to high-speed double-sided print processing a plurality of times.
