Patent ID: 8103204

Claim:
A fixing apparatus for fusing a toner image to a recording sheet, comprising: a fixing roller including an elastic layer; a heating roller including a heat source, the heating roller being formed by sequentially layering an elastic layer and a mold release layer on an outer circumferential face of a shaft; a fixing belt wound around the fixing roller and the heating roller, the fixing belt being formed by sequentially layering an elastic layer and a mold release layer on an endless belt type base material layer formed from heat-resistant resin; and a pressurizing roller that is pressed to the fixing roller via the fixing belt, wherein volume resistivity of the base material layer of the fixing belt is in a range of 10 10 Ωcm to 10 17 Ωcm inclusive, volume resistivity of the elastic layer of the fixing belt is in a range of 10 12 Ωcm to 10 16 Ωcm inclusive, volume resistivity of the elastic layer of the fixing roller is in a range of 10 12 Ωcm to 10 16 Ωcm inclusive, and volume resistivity of the elastic layer of the pressurizing roller is in a range of 10 3 Ωcm to 10 8 Ωcm inclusive.
