ABSTRACT:
This invention provides an apparatus for feeding a flexible, sheet-like transfer medium which comprises an image carrier for carrying a transferable toner image, transfer means for transferring the toner image to the transfer medium by exposing it to an electric charge, guide means arranged to guide the transfer medium to be fed, and a semi-conductive support member for supporting the guide means on an electrically-grounded system body so as to electrically connect the guide means and the body. The apparatus of this invention is capable of preventing the formation of transfer voids and toner smudges on the transfer medium such as might be caused by the leakage of electric charge and the phenomenon of floating toner clinging to the medium.
