Abstract

Bias roll transfer (BTR) systems provide pressure engagement between a copy substrate and toner layer, while creating the transfer field necessary for transfer of toner to the copy substrate. Because of this pressure engagement, BTR systems may solve problems caused by air gaps at the tonerlsubstrate interface when cockled, curled, or other non-flat substrate material is used. For BTR systems to work, it is important to provide a high transfer field in and just past the roller nip, but the allowed fields are typically limited by air breakdown in the area before the transfer ni , often resulting in an image
