Abstract

1461873 Carrier particles for electrostatic developer XEROX CORP 23 Jan 1974 [29 Jan 1973] 03141/74 Heading G2H Carrier particles for an electrostatic developer comprises dispersed particles of a magnetic ceramic material, such as nickel-zinc ferrite, in a matrix comprising at least one of a rubber, a polyvinyl acetate, a polyvinyl chloride, a polymethyl methacrylate, a styrene-butadiene ABA block copolymer or a polytetrafluorethylene. The particles may have an average diameter in the range from 50 to 1000 microns.
