Abstract
A process is provided for increasing the electrostatic transfer efficiency of toner powder from an element to a receiver sheet. The method involves conducting such transfer in the presence of at least one fluorinated onium salt wherein either one or both of the cationic portion and the anionic portion thereof contain a fluorinated hydrocarbon group. Further included are novel toner powders, a novel coated element, and certain new fluorinated onium salt compounds.
