Abstract
Apparatus for enhancing the permanence of printed images. A substrate with a heated, fused toner image is passed by a PTFE powder coated roller for selective contact therewith by a pivotable engagement bar. The PTFE particles are adhered only to the desired imprinted areas and not to the non-printed and non-selected areas of the substrate. The powder is dispensed on a selective basis to the surface of the substrate. The invention also includes the method for enhancing the permanence of a printed image on the substrate.
