Abstract
In a fixing apparatus including 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, volume resistivity of the base material layer of the fixing belt is in a range of 10Ωcm to 10Ωcm inclusive, volume resistivity of the elastic layer of the fixing belt is in a range of 10Ωcm to 10Ωcm inclusive, volume resistivity of the elastic layer of the fixing roller is in a range of 10Ωcm to 10Ωcm inclusive, and volume resistivity of the elastic layer of the pressurizing roller is in a range of 10Ωcm to 10Ωcm inclusive.
