Abstract
A heat roller fixing device has a fixing roller into which a heater is built and a pressing roller which rotatably presses on the fixing roller so that a non-fixed image is fixed on a paper sheet in a nip between the fixing roller and the pressing roller. It also includes a first frame for rotatably supporting the fixing roller, a second frame for rotatably supporting the pressing roller, a harnesses, a temperature detecting device, a safety device and a connector which are provided on the first frame. Positioning members on the first frame position the fixing device relative to the second frame. The strength against bending, the thickness and the heat resistance of the first frame are higher than that of the second frame.
