Abstract: Carriers doubly coated with metal oxide and intended for electrophotography Carriers for electrophotography, based on magnetic cores coated with different metal oxides, have A) a first layer which essentially consists of electrically insulating metal oxide and B) a second layer which essentially consists of metal oxide controlling the electrostatic charging of the toner and which does not substantially decrease the electroresistance of the carriers, which resistance is provided by the layer(A).
