Abstract
To minimize or eliminate a blurred image in xerographic reproduction prior to transfer, a developed image on a charged photoreceptor is first exposed to light to at least substantially discharge the background around the image and to reduce the charge on the photoreceptor holding the image on the photoreceptor, and then a charge opposite to the polarity of the charged photoreceptor is deposited onto the image and photoreceptor. This produces a very stable image for transfer since a very strong holding force is produced to hold the image in place as the image enters a transfer station.
