1. A fixing apparatus comprising:
a heater that includes a substrate, a plurality of heating elements arranged on the substrate along a longitudinal direction of the substrate, and a plurality of electrodes provided on the substrate, each electrically connected to a corresponding one of the plurality of heating elements; and
a plurality of power supply members, each including a first member bonded or coupled to a respective one of the plurality of electrodes to supply power to the corresponding one of the plurality of heating elements and a second member bonded or coupled to a surface of the first member opposite to a surface of the first member that is bonded or coupled to the respective electrode, wherein
the heater generates heat by power supplied via the plurality of power supply members, and an image formed on a recording material is heated by heat of the heater; and
a linear expansion coefficient of each of the first members is different from a linear expansion coefficient of each of the second members.
