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.
