Abstract
When a user has performed an operation with respect to an image forming apparatus, a control mechanism informs that a user has performed an operation with respect to an image forming apparatus to an engine control unit through a dedicated communication line, i.e., without waiting for a general-purpose communication line to open for communication. Upon receiving the user operation signal, the engine control unit heats a fixing unit.
