1. An apparatus for transferring a developed image from an image bearing surface to a copy sheet, including, the apparatus comprising:
a charging station for charging the copy sheet to attract the developed image from the image bearing surface to the copy sheet wherein said charging station includes a corona generating device spaced from the image bearing surface to define a gap therebetween through which the copy sheet passes; a transfer assist blade for pressing the copy sheet into contact with the developed image on the image bearing surface in a region proximate to the charging station, wherein the transfer assist blade is shifted between a non-operative position spaced from the image bearing surface, and an operative position in contact with the copy sheet on the image bearing surface, wherein the transfer assist blade comprises in sequence:
a wear layer for contacting the copy sheet, wherein the wear layer of the transfer assist blade has a surface resistance of greater than about 1010 ohms;an interior layer; anda back layer comprising a thermoset polyimide having dispersed therein carbon particles such that an outer surface of the back layer has a surface resistance of from about 1×108 ohms to about 9.99×108 ohms; and a lever member for shifting the transfer assist blade between the non-operative position and the operative positions responsive to a registration signal. |
