PROBLEM TO BE SOLVED: To provide a fixing apparatus which does not cause poor fixing and hot offset and in which a pre-heat operation time is not extended excessively. SOLUTION: The fixing apparatus includes a control circuit which controls the electrifying to a first heater so that a temperature detected by a first temperature detection portion reaches a first target temperature and controls the electrifying to a second heater so that a temperature detected by a second temperature detection portion reaches a second target temperature, when warm-up is initiated, and, when the warm-up is initiated, if an initial temperature of a fixing roller is below a predetermined temperature, the control circuit sets the first target temperature to a temperature value greater than the first target temperature set when the initial temperature of the fixing roller is greater than the predetermined temperature and sets the second target temperature to a temperature value smaller than the second target temperature set when the initial temperature of the fixing roller is greater than the predetermined temperature.
