ABSTRACT:
An electrostatographic processor having a rotatably driven drum for advancing an imaging surface through successive processing stations, a development system charged with a ferromagnetic developer for developing latent electrostatic images carried by the imaging surface, and a cleaning system including a sump for collecting residual toner removed from the imaging surface is equipped with a toner reclaim system comprising a plurality of permanent magnets which are mounted at spaced apart intervals on one end of the drum to magnetically convey developer from the development system to the cleaning system sump via one non-magnetic conduit and from the cleaning system sump back into the development system via another non-magnetic conduit. The developer blends with the residual toner while passing through the sump of the cleaning system, with the result that its toner concentration tends to increase, thereby causing residual toner to be mechanically and triboelectrically returned to the development system.
