Abstract
In an electrophotographic copying apparatus of the type in which a toner image is transferred from the surface of a photosensitive medium to a transfer medium, a transfer medium separating device comprises a rotatable separating roller disposed downstream of an image transfer station where a toner image is transferred from the surface of the photosensitive medium to the transfer medium, a transfer medium end guide belt disposed in contact with the peripheral surface of the rotatable separating roller for separating one end of the transfer medium from the surface of the photosensitive medium at the image transfer station and for guiding the transfer medium away from the photosensitive medium after the image transfer, and a rotatable pressure roller disposed in pressure contact with the rotatable separating roller for transporting the transfer medium while urging the same against the rotatable separating roller and for separating the transfer medium from the surface of the photosensitive medium.
