Abstract

An image fixing apparatus includes a resistor for generating heat upon electric energy supply thereto; a temperature sensor for sensing a temperature of the resistor; and a control unit for controlling the electric energy supply to the resistor so that the temperature sensor detects a target temperature, in accordance with both of a temperature of the resistor and a resistance of the resistor.
