Abstract

Abstract Translated from German Carrier für einen Zweikomponenten-Trockenentwickler auf der Basis eines ferritischen oder eisenhaltigen Kernes, der eine Metalloxidschicht trägt, die aus in der Gasphase abgeschiedenen Reaktionsprodukten besteht. Carrier for a two-component dry developer based on a ferritic or iron-containing core, which carries a metal oxide layer, which consists of reaction products separated in the gas phase. Die Carrier gemäß der Erfindung weisen abrasionsfeste Metalloxidschichten auf, die elektrostatische Aufladungen in beiden Richtungen erlauben. Durch Einstellen der Dicke der Metalloxidschicht kann die elektrische Leitfähig­keit verändert werden. The carriers according to the invention have abrasion-resistant metal oxide layers which allow electrostatic charging in both directions. The electrical conductivity can be changed by adjusting the thickness of the metal oxide layer.
