| 1. A fixing apparatus comprising:
a heating roller including an elastic member placed on an outside of a shaft member, and a conductive metal layer formed cylindrically
and placed on the outside of the elastic member;
a pressurizing roller pressed to the heating roller; and
a driving mechanism configured to give a rotating force to the conductive metal layer, and to rotate the heating roller;
wherein the conductive metal layer of the heating roller comprises burrs projecting in the axial direction farther than the
elastic member at both ends; and
wherein the driving mechanism includes:
first members placed inside the burrs;
second members outside the burrs, wherein the second members are configured to hold the burrs from the opposite side of the
first members, and to give a rotating force to the conductive metal layer; and
a drive coupled to the second members and configured to supply power to the second members.
