Abstract
An image transfer device includes an image bearing member, a pair of opposed transfer members, a media separator, and an electrical bias applicator. The image bearing member defines an image bearing surface on which a toner image is created. The pair of opposed transfer members is disposed opposite each other via the image bearing member to form a transfer nip therebetween through which a recording medium is passed. One of the transfer members defines a first electrode to which a first electrical bias is applied. The media separator defines a second electrode downstream from the transfer nip to which a second electrical bias is applied. The electrical bias applicator includes a power supply connectable with each of the first and second electrodes to supply the first electrical bias to the first electrode and the second electrical bias to the second electrode.
