Abstract:
1. A fixing apparatus comprising: a heating member which rotates; a pressing member which rotate together with the heating member, while remaining in contact with the heating member, and which exerts a pressure to an object nipped between the heating member and the pressing member; a first coil which performs induction heating at a first region that is a part of the heating member and extends in a direction that intersects at right angles with a direction in which the heating member rotates; a second coil which performs induction heating at a second region that is a different part of the heating member and extends in the direction that intersects at right angles with the direction in which the heating member rotates; a first temperature sensor which detects a temperature T a second temperature sensor which detects a temperature T first control means which causes the first coil and the second coil to operate alternately; and second control means which controls a ratio of an operating time of the first coil to an operating time of the second coil, in accordance with a ratio of the temperature T
