登録請求の範囲第２項記載の加熱定着装置。[Claims for Utility Model Registration] (1) In a fixing device that fixes an unfixed image onto paper using a heat roller and a pressure roller, the heat roller has a core metal and a powder of a low-resistance material on the surface of the core metal. Further, a cleaning means for cleaning the surface of the heat roller is provided on the surface of the heat roller, and a cleaning means for cleaning the surface of the heat roller is provided on the downstream side of the cleaning means in the rotational direction of the heat roller and on both sides. A heat fixing device characterized in that a charge eliminating means is provided upstream of a nip position of the roller to eliminate the electric charge charged on the heat roller. (2) The heating fixing device according to claim 1, further comprising a temperature detecting means for detecting the temperature of the surface of the heat roller between the cleaning means and the static eliminating means. (3) The heat fixing device according to claim 2 of the utility model registration claim, characterized in that the temperature detection means is integrally provided with a cleaning means and a static eliminating means.
