Abstract:
1. A fixing device for thermally fixing an unfixed image onto a recording sheet by causing the recording sheet, with the unfixed image formed thereon, to pass through a fixing nip, the fixing device comprising: a heat belt formed in an endless shape and provided with a resistance heat layer; a first pressure member provided inside a running path of the heat belt; and a second pressure member configured to press the first pressure member via the heat belt from over the running path of the heat belt to form the fixing nip, wherein the first pressure member is shorter than the second pressure member in the axis direction, at least one of the first pressure member and the second pressure member being a rotating body, the heat belt including a pressure-receiving area and two non-pressure areas, the pressure-receiving area receiving pressures from both the first pressure member and the second pressure member, and the non-pressure areas being arranged at outside of the pressure-receiving area in an axis direction of the rotating body, and two ring-like electrodes having been formed on circumferential surfaces of the respective two non-pressure areas and used to supply power to the resistance heat layer.
