摘要: Carriers for a two-component dry developer are based on a ferrite or iron-containing core which carries a metal oxide layer consisting of reaction products deposited in the gas phase.The carriers according to the invention have abrasion-resistant metal oxide layers which permit electrostatic charging in both directions. By adjusting the thickness of the metal oxide layer, the electrical conductivity can be altered.
