摘要：
The present invention provides a fixing apparatus including a rotatable member, a heater for heating the rotatable member, and control means which controls a heat generation of the heater, wherein a toner image on a recording material is heated by the rotatable member, the apparatus has a surface condition changing mode for changing a surface condition of the rotatable member, and, when the surface condition changing mode is selected, the control means controls the heat generation of the heater in such a manner that a surface temperature of the rotatable member becomes equal to or higher than a melting temperature of a surface layer of the rotatable member.
