A fixing device includes a heating member including a base layer, first and second electroconductive layers and a plurality of heat generating resistors provided on the base layer and having a volume resistivity smaller than a volume resistivity of the base layer; a temperature detecting member; and an electrode member. The heat generating resistors are provided helically around the base layer so that a helical axis thereof extends along the longitudinal direction of the rotatable member, and are disposed with intervals. One end and the other end of each of the heat generating resistors are electrically connected with the first and the second electroconductive layers, respectively. A temperature detecting region of the rotatable member by the temperature detecting member overlaps with the heat generating resistors. |
