Abstract (en)

Disclosed is a method for developing electrostatic latent images, which comprises frictionally contacting the surface of a substrate (5) having an electrostatic latent image formed thereon with a magnetic brush of a developer formed on a developer-delivering sleeve (2) having a magnet (1) disposed therein, wherein a magnetic brush is formed on the sleeve with an earing promoting component comprising sintered ferrite particles (4) having a particle size of 20 to 100 microns and a developer component (3) comprising particles of a dispersion of a magnetic powder in a binder medium having a particle size of 5 to 50 microns.
