ABSTRACT:
Method and means is disclosed for treating carrier particles in order to change the charge to mass ratio and the resistivity of a development powder encompassing such particles. The carrier particles are first coated with a polymer capable of providing reactive sites and then an additional treatment is carried out with a material that will react to the reactive sites. Another advantage of the treatment is that the carrier particles are protected from oxidation following such treatment.
