ABSTRACT:
A method for preparing the carrier for a developer composition is provided. The method comprises subjecting a ferric oxide and a metal oxide to conditions sufficient to form a ferrite have a spinel structure, mixing the ferrite having a spinel structure with a sintering agent, and sintering in the liquid phase the mixture at temperature conditions of less than about 1375.degree. C. to provide a ferrite carrier devoid of zinc, copper, or nickel in its crystal structure. The ferrite carrier cab be used in a developer composition comprising the ferrite carrier and a toner composition.
