<p>The present invention relates to a method of transferring a toner image to a copy medium (12) and more specifically to a structural arrangement in a printing machine of the type having a toner image interposed between a flexible member (7, 18) and the copy medium (12). The printer has a device (10) for transferring the toner image from the flexible member (7, 18) to the copy medium (12), an apparatus (16) separating the copy medium (12) from the flexible member (7, 18), and a device, located intermediate the transfer device (10) and the apparatus (16), for providing a relative motion between the copy medium (12) and flexible member (7, 18) so as to reduce short range surface forces and permit electrostatic forces between the toner and flexible member (7, 18) to dominate for improving transfer efficiency. The device for providing relative motion creates a non-tensioned buckle (30) in the portion of the flexible member (7, 18) located intermediate the transfer device (10) and the apparatus (16) so as to form the non-tensioned condition in the buckle portion (30) of the flexible member (7, 18) and a tensioned condition in the remainder of the flexible member (7, 18). <IMAGE></p> |
