ABSTRACT:
An electronic duplicator machine heats a toner attached to a copying paper and a fixing device fixes the toner to the paper. The fixing device includes a heat generating roller which includes a supporting body having a journal portion on either end surface and rotatably supported by the journal portion; a heat insulating layer formed on the outer circumferential surface of the supporting body to prevent the transmission of heat to the supporting body; a resistance heater layer through which a current flows to heat the toner and which covers the outer circumferential surface of the heat insulating layer.
