Abstract
Apparatus and method for reducing toner rub-off from a copy made by an electrophotographic process wherein printers' anti-offset powder (e.g. finely-powdered starch) is sprayed onto the copy after the toner image has been fused to the copy. If a release oil is present on the copy, the powder is sprayed directly onto the release oil on the copy. To apply the powder, an applicator is positioned within the finishing section of the electrophotographic apparatus and sprays the copy with the powder as the copy exits the fuser section of the apparatus.
