ABSTRACT:
Apparatus for electrostatically transferring a transferable image from an image-carrying member to a receiver member. The transfer apparatus includes a resilient, deformable electrically conductive member adapted to be connected to a source of electrical image transferring potential. The conductive member defines a passage connectible to a vacuum source for vacuum tacking a receiver member to a surface of such member. Such passage has a longitudinal axis which, at the surface of conductive member, defines an oblique angle to such surface. During image transfer, the conductive member deforms during pressure contact with the image-carrying member to eliminate the surface discontinuity at the passage opening so that an electrical transfer potential is uniformly applied to the receiver member.
