Abstract:
1. A fixation device comprising: a fixation member configured to include a heating member; a pressure-application member configured to press-contact the fixation member to form a nip portion therebetween; an exciting coil configured to induction-heat the heating member of the fixation member; a first temperature detection unit configured to detect a first temperature of the pressure-application member; a second temperature detection unit configured to detect a second temperature of the fixation member; a third temperature detection unit configured to detect an ambient temperature in the neighborhood of the fixation member; and a control unit, wherein the control unit, upon receiving a signal indicating that current has been applied to the exciting coil, wherein the control unit controls electric power supplied to the exciting coil, wherein a reference temperature for transitioning from the power control mode to the temperature control mode, and a target temperature of the fixation device in the temperature control mode are set for the second temperature of the fixation member detected by the second temperature detection unit.
