Abstract
A charging apparatus for modulating the distribution of available charge to a charge retentive surface. The charging apparatus includes a coronode wire positioned a predetermined distance away from the charge retentive surface and a charge stream dividing rod positioned between the coronode and charge retentive surface. The charge stream dividing rod has a conductive core and an insulating sheath overcoating the conductive core. Preferably, the conductive core is AC biased in order to sweep ions from the coronode wire back and forth over the charge retentive surface.
