摘要： There is provided an image forming apparatus which adopts a distributed control system and increases the error detection accuracy of each control unit. To accomplish this, the image forming apparatus includes a master control unit that controls the overall image forming apparatus, a plurality of sub-master control units that control a plurality of functions for performing image formation, and a plurality of slave control units that control loads for implementing a plurality of functions. The master control unit determines a diagnosis path for performing a diagnosis process for an error using the signal lines and a connection bridge connected to the respective control units. The master control unit performs the diagnosis process for an error in accordance with the determined diagnosis path.

摘要： The image forming apparatus has the plurality of control units and executes distributed processing in which any one control unit having monitoring execution authority monitors for an abnormal condition in each control unit. Each control unit determines, from its own processing load, monitoring capability information that indicates whether monitoring for an abnormal condition is possible or not. If, in a case where the control unit has the monitoring execution authority, the monitoring capability information does not satisfy predetermined information, then the control unit delegates the monitoring execution authority to another control unit whose monitoring capability information does satisfy the predetermined information.
