<p>A self biasing transfer member (10) for transferring toner particles (17) from an image support surface (15) to a copy substrate (16), including a conformable layer (13) and a layer (14) of piezoelectric material thereover which generates an electric field when deformed. In one embodiment the transfer member is a roll (10) having an axial core (12) about which the conformable layer is cylindrically formed, and the piezoelectric material is a film circumferentially surrounding the conformable layer. The transfer member is urged against the imaging support surface to form a nip (22) which causes the conformable layer to conform thereagainst and deform the piezoelectric material. In another embodiment, a blade (50) is used to clean and deform the transfer member. <MATH></p> |
