Abstract
A heating unit includes a heater including a substrate and a resistance heating element provided on the substrate, an endless belt configured to rotate around the heater, a thermostat configured to interrupt energization to the resistance heating element when the heater is abnormally increased in temperature, the thermostat having a heat sensitive surface and a heat-insulating member disposed between the thermostat and the heater. The heat-insulating member has a heat conductivity less than that of a material constituting the heat sensitive surface. The heat sensitive surface of the thermostat is in contact with the heat-insulating member.
