ABSTRACT:
A magnetic brush and developing process in which the same magnetic brush is used for developing electrostatic latent images and for cleaning the developing surface. The process includes the steps of (a) providing a magnet roll which includes a rotatable, non-magnetic cylindrical shell and a rotatablepermanent magnet disposed within the shell; (b) forming a magnetic brush of a developer power on the shell of the magnetic roll; (c) developing electrostatic latent images by softly rubbing the magnetic brush against electrostatic latent images on an image bearing surface; (d) transferring the developed images to a sheet; and (e) cleaning the image bearing surface by strongly rubbing the magnetic brush against the surface.
