There is provided a heating controlling device having: a receiving section receiving heating instructions for plural heaters; and a controller that, when the receiving section receives a heating instruction to heat another heater while two or more heaters other than the heater for which the heating instruction is received are heating, stops heating of the heaters that are heating, after a first predetermined time period elapses from the control to stop heating, starts heating of the heater for which the heating instruction is received, and each time a number of second predetermined time periods elapses from the control to start heating, restarts heating, on the basis of predetermined priority rankings, of the heaters that were controlled to stop heating.

Heating controlling device, heating device, image forming device, program storage medium, and method

A heating apparatus of the present invention includes a press member that undergoes driven rotation by contacting a heating member that rotates, the press member conveying a recording medium while nipping the recording medium between the press member and the heating member; a contact and separation mechanism that contacts the press member against the heating member and separates the press member away from the heating member; and a drive mechanism that rotationally drives the press member when the press member is separated from the heating member by the contact and separation mechanism.

Heating apparatus and image forming apparatus

A fixing device includes a heater; a fixing rotary body having a circumferential surface which paper carrying an unfixed image makes contacts with and passes on, and heated to a predetermined temperature by a heating operation of the heater; a temperature detecting unit which detects the temperature of a portion of the circumferential surface inside a widest paper passage region in an axial direction of the fixing rotary body; a control unit which stops the heating operation of the heater when a temperature detected by the temperature detecting unit exceeds a predetermined overheat temperature; and a measuring unit which measures a continuous heating time from a point of time when the heating operation of the heater starts. The control unit stops the heating operation of the heater when the continuous heating time measured by the measuring unit exceeds a predetermined scheduled heating time.
