Fixing belt, fixing device, and image forming apparatus

Provided is a fixing belt including a base layer, an elastic layer, and a release layer. The release layer has surface geometry including a first uneven profile and a second uneven profile formed on the surface of the first uneven profile. The first uneven profile is represented as a maximum height roughness, Rz, of 5.0 to 100 &#x3bc;m. The second uneven profile is represented as Rz of 0.5 to 0.9 &#x3bc;m.

A fixing belt includes a base layer, an elastic layer made of an elastic material, and a release layer. The elastic layer includes a first elastic layer disposed on a side of the base layer, and a second elastic layer disposed on a side of the release layer. The second elastic layer has a lower hardness than that of the first elastic layer. A Universal hardness of the second elastic layer is 3 to 7 N/mm. A thickness ratio of the second elastic layer to the elastic layer is 5 to 15%.

A fixing belt includes a base layer made of a heat-resistant resin, an elastic layer made of an elastic material, and a releasing layer, which are laminated in this order, and the difference between the maximum value and the minimum value of viscoelastic modulus within a range of 100 to 200&#xb0; C. is 0.8% or less. Further, the viscoelastic modulus of the fixing belt within the range of 100 to 200&#xb0; C. is within a range of 50 to 62%.
