Abstract
Disclosed is a fixing apparatus which includes a first rotatable member having an endless configuration, and a second rotatable member in pressure contact with the first rotatable member which causes a recording material bearing an image to be nipped and conveyed at a pressure contact portion between the first and second rotatable members. A temperature raising unit is provided for raising temperature of a local portion of the first rotatable member by reception of electric power supply, and a temperature detecting unit detects a temperature of a location different from the pressure contact portion with respect to a rotational direction of the first rotatable member. A first control unit is provided for feedback-controlling electric power to be supplied to the temperature raising unit, and a second control unit is provided for temporally supplying electric power corresponding to a set value set by a setting unit to the temperature raising unit.
