CARRIER FOR COPYING SYSTEMS AND MANUFACTURING PROCESS THEREOF

摘要

A carrier for a dry two-component developer based on a ferritic or iron-containing core carries a metal oxide layer which consists of reaction products deposited from the gas phase. …The carriers according to the invention have abrasion-resistant metal oxide layers which permit electrostatic charging in both directions. The electrical conductivity can be varied by adjusting the thickness of the metal oxide layer.
