PROBLEM TO BE SOLVED: To solve such a problem that a heater having a substrate, and a heat generating part consisting of two conductor patterns provided on the substrate and having different longitudinal lengths, and a heat element provided between the two conductor patterns on the substrate may sometimes generate left/right temperature unevenness caused by the lengths of the two conductor patterns.SOLUTION: A first heat-generating part and a second heat-generating part, which are two heat generation parts consisting of a heat element provided on a substrate, with it sandwiched between two conductor patterns having different lengths, are aligned in a short-side direction of the substrate along the longitudinal direction of the substrate. A longitudinal end part of the longer-length conductor pattern of the first heat-generating part and an end part of the shorter-length conductor pattern of the second heat-generating part that is close to the end part of the first conductor pattern are electrically connected, where the first heat-generating part and the second heat-generating part are electrically serially connected. |
