ABSTRACT:
Disclosed is a heat roller fixing apparatus for performing a thermal fixation onto a sheet by rotating a heat roller. This heat roller fixing apparatus comprises a heat roller including a roller body and a plurality of heating members provided in the roller body and a pressurizing member provided in a face-to-face relationship with the heat roller. This heat roller fixing apparatus has a rotation mechanism for rotating the plurality of heating members along an inner periphery of the roller body and a control unit for drive-controlling the rotation mechanism during a standby status for driving the heating members without rotating the roller body. An unevenness in preheating on the surface of the roller body of the heat roller is thereby prevented.
