Abstract

Electrostatographic conductive coated carrier particles for use in the development of electrostatic latent images are provided by preparing a fluid mixture of insulating resinous material and an electrically conductive agent, converting the fluid mixture to a solid state, and comminuting the solid mixture to dry, powdered particles having a particle size of 1 to 100 microns. The powdered particles are mechanically or electrostatically applied to the surface of carrier cores having a particle size of 30 to 1000 microns. The resultant aggregation is heated to melt and fuse the powdered particles to the surface of the carrier cores. The conductive carrier particles are mixed with finely-divided toner particles to form developer mixtures.
