Abstract
A biased roller electrostatographic image transfer system in which concentrated and tailored image transfer fields are generated by stationary electrically biased conductive electrodes inside the roller having blade-like edges extending toward the nip and post-nip areas, in which the transfer fields are applied from the blade-like edges through a thin-walled rotatable outer tube providing the roller nip.
