Abstract
A temperature control device for controlling a surface temperature of a member to be heated at a predetermined temperature includes a detector for detecting the surface temperature, and a control unit for controlling current supply for a heating source for heating the member to be heated so that a result of detection by the detector is maintained at a predetermined value. The control unit controls a time of current supply for the heating source during a constant temperature control according to data relating to peak temperatures of the surface temperature during the constant temperature control.
