Abstract:
1. An image forming apparatus including a plurality of image forming stations which form toner images on a page on the basis of a job for forming an image, the apparatus comprising: a discrimination unit adapted to discriminate whether a condition to perform adjustment processing for parameters of the plurality of image forming stations during an image forming operation of a plurality of pages based on the job is satisfied; a determination unit adapted to, in a case where said discrimination unit discriminates that the condition to perform adjustment processing is satisfied, determine whether at least one of the plurality of image forming stations has a non-operating time period long enough to execute adjustment processing satisfying the condition during the image forming operation of the plurality of pages; and a control unit adapted to perform the adjustment processing to the at least one of the plurality of image forming stations having the non-operating time period long enough during the non-operating time period, wherein said determination unit determines the non-operating time period of each of the plurality of image forming stations during the image forming operation of the plurality of pages, and wherein said determination unit determines a continuous non-operating time period of an image forming station among the plurality of image forming stations that does not form an image during image forming operations of the remaining image forming stations.
