An image forming apparatus for accepting print jobs, determining the execution order of received jobs, and executing the jobs in the determined order manages an unspecified job priority as the execution priority of an unspecified job for which a value that affects the order of execution is not specified. The image forming apparatus can accept a priority-specified job for which an execution priority is specified and an unspecified job. The image forming apparatus determines the order of execution of this priority-specified job on the basis of the priority specified in the priority-specified job, and determines the order of execution of the unspecified job on the basis of the unspecified job priority, and can accept a specification of the unspecified job priority.
