ABSTRACT:
Electrostatographic carrier particles with improved conductivity and stability are prepared from magnetic stainless steel particles. The particles are treated by submersion in an aqueous oxalic acid solution. The passivated stainless steel carrier particles, preferably after being first coated with a resin, may then be mixed with toner powder for electrographic dry development.
