Abstract
A fixing unit includes: a heat roller that is rotatably supported and that supplies heat for fixing; and a first and a second tubular heaters that are disposed in parallel in the heat roller along an axis thereof and that each have on an outer circumferential surface thereof one protruding residual fused tip, namely, tip portion. As viewed from a side end surface of the heat roller, the tip portions of the first and second tubular heaters are oriented directly opposite to each other with respect to the connection line connecting centers of the first and second tubular heaters.

A fixing unit comprising:
- a heat roller that is rotatably supported and that supplies heat for fixing;
- and
- a first and a second tubular heaters that are disposed in parallel in the heat roller along an axis thereof, the first and the second tubular heaters each having on an outer circumferential surface thereof one protruding residual fused tip, namely, tip portion,
- wherein, as viewed from a side end surface of the heat roller, the tip portions of the first and second tubular heaters are oriented directly opposite to each other with respect to a connection line connecting centers of the first and second tubular heaters.
A fixing unit comprising:
- a heat roller that is rotatably supported and that supplies heat for fixing;
- and
- a first and a second tubular heaters that are disposed in parallel in the heat roller along an axis thereof, the first and the second tubular heaters each having on an outer circumferential surface thereof one protruding residual fused tip, namely, tip portion,
- wherein the first tubular heater has:
- lead wires protruding outwardly from both axial side end surfaces thereof, and flat terminals located on a side of the tip portion as viewed form the side end surfaces and soldered to the lead wires,
- wherein the second tubular heater has:
- lead wires protruding outwardly from both axial side end surfaces thereof, and flat terminals that are located on a side opposite to the tip portion as viewed form the side end surfaces and that are soldered to the lead wires, and
- wherein, as viewed from a side end surface of the heat roller, the tip portions of the first and second tubular heaters are oriented directly opposite to each other with respect to a connection line connecting centers of the first and second tubular heaters, and the connection line coincides with a center line of the heat roller.
