Abstract

Triboelectrically negatively charged electrophotographic carrier for use in a developer mixture for the electrostatic latent image formed on a photo-conducting element, consisting of a number of carrier pellets consisting of a particulate core and external coating of a resin comprising a major proportion of sintered and agglomerated particles forming a continuous phase of a fluorocarbon compound fully substd. with fluorine.
