ABSTRACT:
Apparatus for enhancement of image transfer including an image bearing surface and a second surface arranged for relative movement along a pathway whereby portions of the image bearing surface and the second surface sequentially come into propinquity and subsequently move out of propinquity, potential impression means associated with at least one portion of at least one of the image bearing surface and the second surface for impressing a potential on the at least one portion, and means for energizing the potential impression means only when such portions are located at predetermined locations along the pathway, thereby to provide image rigidization.
