| 1. A fixing apparatus comprising:
a first heating member that is provided with a first heating layer formed of a non-magnetic metal;
a second heating member that is provided with a second heating layer formed of a magnetic metal; and
an exciting coil that is disposed inside the first heating member,
wherein the first and the second heating members make contact with each other to form in between a nip portion through which
a medium on which fixing is performed is passed, and
the exciting coil is disposed near the nip portion so as to make the first heating layer and the second heating layer generate
heat in a first heating section near the nip portion when the exciting coil is energized.
