Abstract
A heat insulating layer is provided between the stay and the ceramics heater in a heat fixing device. The heat conductivity of the heat insulating layer is lower than that of the stay. The heater includes a heating element provided on an aluminum nitride substrate. The heater is especially arranged with the heating element facing toward the stay, and with the substrate facing away from the stay and contacting a heat transfer film for conducting heat to a paper sheet or the like on which a toner image is to be fixed.
