ABSTRACT:
In a multi-color imaging apparatus utilizing a recharge step between two image creation steps for recharging a charge retentive surface to a predetermined potential pursuant to forming the second of the two images, a first corona generating device recharges the charge retentive surface with a direct current to a higher absolute potential than a predetermined potential, a second corona generating device recharges the charge retentive surface with a direct current to a lower absolute potential than the predetermined potential, and then a third corona generating device recharges the surface, also with a direct current, to the predetermined potential. An electrical charge associated with the first image is prevented from reversing its original polarity after being recharged by the third corona generating device, thereby preventing the occurrence of under color splatter of the toner image.
