<p>Apparatus for electrostatically transferring a transferable image of electroscopic marking particles from an image-carrying member (F) to a receiver member (R). The apparatus comprises an electrically conductive member (28), such as a roller, selectively coupled to a source of electrical image-transferring potential. Such conductive member is adapted to have a receiver member attached to its surface, and includes a mechanism (30a) for registering an image-carrying member relative to an attached receiver member. A compliant member (44), such as a back-up roller having a resilient deformable peripheral surface, engages the conductive member to define an extended nip. An image-carrying member is guided into engagement with the registration mechanism of the conductive member and then through the extended nip, where a transferable image on such image-carrying member is transferred to such attached receiver member when image-transferring potential is coupled to the conductive member. The extended nip area resulting from the compliant nature of material of the back-up roller increases the time the receiving member and the image-carrying member are in transfer relation thereby improving the effectiveness of the transfer process.</p> |
