Abstract:
1. A fixing apparatus, comprising: a heating member which has a cylindrical shape and has a conductor to flow an induced current by induction heating; a pressing member which supplies a pressure to the heating member; a first induction heating mechanism including a first coil which is arranged opposite to an outer surface of the heating member, the first coil having a first end portion which is inclined to a circumferential direction of the heating member; a second induction heating mechanism including a second coil which is arranged opposite to an outer surface of the heating member and is aligned with the first induction heating mechanism in an axial direction of the heating member, the second coil having a second end portion which is inclined to the circumferential direction of the heating member and opposes to the first end portion of the first coil, the second end portion being overlapped with the first end portion in the circumferential direction of the heating member; and a temperature detection mechanism which cuts off a power supplied to the first and second coils when a temperature of the heating member reaches an abnormal value, the temperature detection mechanism including a first detector which is arranged between the first and second ends of the first and second coils and detects the temperature of the heating member.
