METHOD OF DEVELOPING ELECTROSTATIC IMAGES

摘要

In developing an electrostatic image by bringing an electrostatic image-carrying surface of a substrate (5) into sliding contact with a magnetic brush of a developer formed on a developer-feeding sleeve (2) having a magnet (1) arranged in the interior thereof, problems associated with earing of the magnetic brush are overcome by forming the magnetic brush from an earing-promoting component (4) comprising particles having a diameter of 70 to 300 microns of a dispersion of a powder of a magnetic material in a resin and a developer component (3) comprising particles having a diameter of 5 to 50 microns of a dispersion of a powder of a magnetic material in a binder medium.
