Abstract

To create an overcoat on a toner image, a clear heat softenable particulate material is applied to a fusing surface before the fusing surface contacts the toner image in a fusing nip. The particulate material softens in the fusing process and ends up as a clear overcoat for the toner image, protecting it from scratches, fingerprints, deglossing and/or softening from heat.
