ABSTRACT:
A carrier core for use in an electrostatographic developer composition is a ferrite substantially free of copper and zinc. By being substantially free of copper and zinc, the carrier core is environmentally friendly and eliminates the need for use of conventional copper zinc carrier cores which must be handled as hazardous waste. Developer compositions employing the ferrite carrier core possess suitable properties.
