ABSTRACT:
A temperature controller forcibly stops an operation of a heating member when a detected temperature detected by a temperature sensor reaches a predetermined heating interruption temperature in an initial temperature rising state. Thereafter, when the detected temperature reaches a standby control temperature, or when a predetermined heating interruption period elapses from when the operation of the heating member is forcibly stopped, the drive operation of the heating member is controlled based on the detected temperature and the standby control temperature from when the detected temperature reaches the predetermined standby control temperature lower than a target temperature until a predetermined standby control period elapses.
