Claim 5:
6. A fixing belt comprising:
a base member having a cylindrical shape and containing a metal;
a sliding layer having an inner circumferential surface as a sliding surface side, having an outer circumferential surface formed on an inner circumferential surface side of the base member, and containing a filler, wherein the outer circumferential surface to the inner circumferential surface form a thickness in a thickness direction; and
a separation layer formed outside an outer circumferential surface side of the base member,
wherein the sliding layer is a thermosetting resin that contains 20 to 95% by volume of a solvent in a precursor solution before being cured by heat, the sliding layer is formed through a drying process for volatilizing the solvent, and a shape of the precursor solution is maintained by an increase a viscosity of the precursor solution from a predetermined reduction in the volume of the solvent after the solvent is cured by heat.
