Abstract
An electrostatographic imaging process comprising the steps of providing an electrostatographic imaging member having a recording surface, forming an electrostatic latent image on the recording surface, and contacting the electrostatic latent image with a developer mixture comprising finely-divided toner particles electrostatically clinging to the surface of carrier particles having an average particle diameter of between about 50 microns and about 1,000 microns. The carrier particles consist essentially of a metallic core coated with a thermoset crosslinked acrylic resin to form an adherent durable film of said resin on said core. The acrylic resin consists essentially of esters of acrylic and methacrylic acids selected from the group consisting of a hydroxyl-functional resin crosslinked with nitrogen resins, a carboxyl-containing polymer crosslinked with epoxy resins, and a carboxyl-containing polymer which has been cured with melamine-formaldehyde resins.
