Abstract
A carrier particle for electrostatographic developer mixtures comprising a core having an average diameter between 30 and 1,000 microns surrounded by an outer layer of polymeric vinyl pyridine and an organo silane, silanol or siloxane having from 1 to 3 hydrolyzable groups and an organic group attached directly to a silicon atom containing an unsaturated carbon-to-carbon linkage. The carrier particle is used with small finely-divided toner particles to develop electrostatic latent images.
