ABSTRACT:
In a fixing device employed in an electrophotographic imaging apparatus for fusing an unfixed toner image carrier on a recording sheet, a heat roller and a back-up roller are provided. The heat roller is provided with a heater mechanism installed therein, wherein the heater mechanism is arranged such that the temperature of a portion of the heat roller corresponding to the passing area of the recording sheet is higher than that of the other portions of the heat roller so that the temperature distribution of the heat roller heated by the heater mechanism becomes substantially uniform along its axial direction while the recording sheet is passing through the nip between the heat roller and the back-up roller.
