An image forming apparatus has a print engine, a job issuing device, two print control devices that control the print engine, and a job assignment device that assigns the print job to one of the two print control devices that is appropriate for the print job. Each print control device notifies the print engine of print information corresponding to the print job and manages already-indicated latest information, which is the latest print information. The print information is different from the already-indicated latest information. When making a switchover between the two print control devices to select a switched-to print control device, which is a print control device to which to assign the print job, the job assignment device causes the switched-to print control device to delete the already-indicated latest information managed by the switched-to print control device.
