Abstract
In a main controller of an image forming apparatus, the status renewing-and-notifying unit (a) obtains statuses from a queue, and store status values at addresses corresponding to status IDs in a first status storage unit; (b) notifies a component of both of a objective status and a dependent status either at a same time or in a reversed time order if the statuses includes the objective status and the dependent status, and the status value of the dependent status in the first status storage unit and the status value of the dependent status in the second status storage unit are different from each other; and (c) stores a status value of each status that the component is notified of at an address corresponding to a status ID of the status in the second status storage unit at a notification timing of the status.
