FIXING APPARATUS AND ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS HAVING CERAMIC HEATER HAVING ELECTRICALLY INSULATING LAYER WITH HIGH THERMAL CONDUCTIVITY
|Owner||HEWLETT-PACKARD DEVELOPMENT COMPANY, L.P. (USA)|
AbstractA heater for a fixing apparatus to heat an unfixed image on a recording medium, the heater including a planar shaped electrically insulating substrate including a first surface and a second surface facing each other; a heat generating layer on the first surface of the substrate; an electrically insulating layer to cover the heat generating layer, the electrically insulating layer having a thermal conductivity of at least 100 W/m. K; and a sliding layer on the second surface of the substrate.
