Abstract: PURPOSE: To obtain a wear resistant carrier causing no trouble as a photoconductor by forming metal oxide layers made of reactional product deposited form a vapor phase on core particles made of ferrite or contg. metal iron. CONSTITUTION: A volatile metallic compd. is allowed to react with oxygen and/or water at an elevated temp. in the presence of moving core particles to obtain the objective carrier for a two-component dry developer with metal oxide layers on the core particles made of ferrite or contg. metal iron. For example, iron oxide or titanium dioxide layers are uniformly formed on the core particles. The carrier has the wear resistant metal oxide layers and enables positive and negative charging. Since the thickness of the metal oxide layers can be regulated in accordance with the purpose, electric conductivity can be determined in a specified range independently of the compsn. of the core particles.

Abstract: A plateletlike two-phase pigment which has a core with a hematite structure of the composition AlxFe2-xO3 where x is from 0.02 to 0.5, and an outer layer with a spinal structure of the composition AlyFe3-yO4+z where y is from 0.03 to 0.75 and z is from 0 to 0.5, can be prepared by a hydrothermal treatment of plateletlike AlxFe2-xO3 pigments (x from 0.02 to 0.5) in the presence of a reducing agent dissolved in the aqueous phase.
