Abstract
A fixing device includes a fixing belt comprising a first metal heat generating layer, a pressurizing unit which faces an outer circumference of the fixing belt, an induced current generating coil located within a hollow part of the fixing belt, a nip forming member which pressurizes the fixing belt to the pressurizing unit, and an auxiliary heat generating member located in a periphery of the fixing belt and comprising a second metal heat generating layer.
Claims18
A fixing device comprising:
- a fixing belt comprising a first metal heat generating layer;
- a pressurizing unit which faces an outer circumference of the fixing belt;
- an induced current generating coil located within a hollow part of the fixing belt;
- a nip forming member which pressurizes the fixing belt to the pressurizing unit;
- and
- an auxiliary heat generating member located in a periphery of the fixing belt and comprising a second metal heat generating layer.
An image forming apparatus comprising:
- an image forming unit which forms an image on a recording medium;
- a fixing belt comprising a first metal heat generating layer;
- a pressurizing unit which nips the recording medium between the pressurizing unit and the fixing belt and carries the recording medium;
- an induced current generating coil located within a hollow part of the fixing belt;
- a nip forming member which pressurizes the fixing belt to the pressurizing unit;
- and
- an auxiliary heat generating member located in a periphery of the fixing belt and comprising a second metal heat generating layer.
A fixing method comprising:
- generating an induced current within the hollow part of the fixing belt in a state where, the fixing belt is pressurized toward a pressurizing unit from within a hollow part of a fixing belt, by a nip forming member;
- and
- heating the fixing belt, an auxiliary heat generating member located in a periphery of the fixing belt, and the nip forming member with the induced current.
