Abstract
A heating unit includes a heater including a substrate and a resistance heating element, a temperature sensor, an endless belt, a holder, a first heat conductive sheet located between the heater and the holder, and a second heat conductive sheet which is smaller than the first heat conductive heat member. The first heat conductive sheet includes a first heater-side surface which is in contact with a back surface of the heater and a first opposite surface. The first heat conductive sheet has a heat conductivity higher than that of the substrate. The second heat conductive sheet includes a second heater-side surface which is in contact with the first opposite surface and a second opposite surface. The temperature sensor is in contact with the second opposite surface of the second heat conductive sheet.
