Abstract

1510281 Magnetic brush development MITA INDUSTRIAL CO Ltd 5 Feb 1976 04566/76 Heading B2L In electrophotographic development, a onecomponent, magnetic, conductive or semi - conductive developer is retained on the surface of a member having an insulating surface coating of resistance # 10<SP>3</SP> ohms/cm<SP>2</SP> by means of a magnet within the member and brought into contact with a latent image to develop it. Said member may be a cylindrical sleeve about a magnet, the body of the sleeve being A1, and its coating being polystyrene, polyethylene terephthalate or Al 2 O 3 . The developer may have particle size 3-20Á and the particles may be ellipsoidal.
