Abstract
An apparatus for transferring a plurality of toner images having a charge thereon from a photoconductive member to a receptor sheet, the transferring device including a first corona generator for applying a charge to the sheet of polarity opposite to that of the charge on the corresponding toner image and for transferring the toner image from the member to the sheet, a second corona generator, located after the first corona generator, for applying a charge to the toner image on the sheet of a polarity equal to that of the charge on the toner image for increasing the charge thereof, and a grounding electrode opposite to the second corona generator for electrically grounding the opposite side of the receptor sheet.
