ABSTRACT:
The invention provides a method of modifying the triboelectric charging propensity of carrier particles coated with a fluorohydrocarbon polymer. The method comprises dehydrofluorinating and oxidizing the polymer by contacting the coated particles with a basic solution and a solution of an oxidizing agent. The resulting new particles have less fluorine atoms bonded to the coated polymer and also have oxygen atoms bonded thereto.
