ABSTRACT:
Electrostatographic developer comprised of a toner and an uncoated carrier wherein the carrier is a Group IV metal oxide or a double oxide of tin, hafnium, germanium, zirconium, or titanium and an alkaline earth or lead. These carriers have the desirable properties generally associated with the coated carriers heretofore employed in the art, but are not as prone as the coated carriers to degradation and impactation and therefore have a longer useful life.
