Abstract
In a fixing device, a metal member is provided inside a fixing belt to heat the fixing belt. A first lubricant is applied between the metal member and the fixing belt at a center portion of the fixing belt in an axial direction of the fixing belt that contacts a recording medium bearing a toner image. A second lubricant having a viscosity greater than a viscosity of the first lubricant is applied between the metal member and the fixing belt at lateral edge portions of the fixing belt in the axial direction of the fixing belt that do not contact the recording medium.
