Abstract
A method for modifying the triboelectric charging propensity of particles coated with fluorohydrocarbon polymer for use as carriers in electrostatographic development comprising contacting the particles with a basic solution including a reducing agent for said particles and optionally including an oxidizing agent for said particles and carriers and developers produced by that method.
