Abstract

A carrier particle for electrostatographic developer mixtures may be provided by surrounding a core having an average dia-meter between 30 and 1,000 microns with 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 un-saturated carbon-to-carbon linkage. The carrier particle is used with smaller finely-divided toner particles to develop electrostatic latent images.
