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 frame. The positioning members are horizontally located on a line passing through the center of the fixing roller.
