ABSTRACT:
An electrically self-propelled pulsating multi-directional magnetic brush having an insert for use in toner deposition or removal devices associated with imaging machines of the electrostatic type (dry or liquid), the magnetic type, and the reprographic type. The insert further has skewed magnetic sections, made of permanent magnets or electro-magnets, therearound. The insert is used in conjunction with a permanent or electro-magnet and is contained within a rotatably mounted drum to provide an insulation for the drum and to further provide a driving force to uniformly rotate and multi-directionally pulsate developer mixture material around the drum.
