Abstract: An image forming system cyclically conveys an Nth sheet with an image formed on a first side to an image forming unit as a sheet subject to image formation after image formation on a subsequent (N+i)th sheet, and form an image on a second side of the Nth sheet. The system includes an obtaining unit that, during image forming processes, obtains respective updated adjustment values for the first and second sides, and a control unit that performs control to simultaneously store the updated adjustment value for the first side and an unupdated adjustment value for the second side in a part of a period of the processes, form an image on the first side of the (N+i)th sheet using the updated one for the first side, and form the image on the second side of the Nth sheet using the unupdated one for the second side.

Abstract: An image reading apparatus includes a reading unit, an interrupt unit, a control unit, and a selection unit. The reading unit reads an original document. The interrupt unit interrupts a first read job for reading a first original bundle by the reading unit. The control unit executes a second read job, different from the first read job, for reading a second original bundle, different from the first original bundle, by the reading unit while the first read job is interrupted by the interrupt unit. The selection unit selects, from among one or more read jobs interrupted by the interrupt unit, a selected read job to be resumed after the second read job of the second original bundle is completed.
