ABSTRACT:
A solid-state selectably switchable combination cascade/magnetic brush for use in toner deposition or removal devices used in imaging machines of the electrostatic or magnetic type having one or more electro-magnets with one or more electro-magnetic windings and transfer heads placed inside, as well as outside, a photoconductor. Imaging mixture is agitated and conveyed to a transfer head which is exposed and adjacent to a photoconductor thereby eliminating the need for a drum or sleeve as the carrier/deposition agent for the imaging mixture. Transfer heads deposit imaging mixture directly onto a primary development zone with the excess cascading and attracting to a residual development zone and/or reclamation structure.
