Abstract
In a xerographic printing apparatus, toner material is thermally fused and fixed onto a surface of a copy sheet by condensing water vapor on the surface of the copy sheet. In the preferred embodiment, the toner material substantially comprises docasanoic acid. The water vapor is condensed on the surface of the copy sheet by means of applying the water vapor onto the surface through a narrow slit moving relative to the surface.
