A device for transferring images from an image donating member to an image receiving medium comprises a substrate, at least two electrodes disposed on the substrate, and at least one layer of coating disposed on the substrate having an outer surface for forming a nip region with the image donating member. The at least two electrodes are controllable to produce an electric field and control a position thereof at the nip region to allow transfer of an image from the image donating member to the image receiving medium in an image transfer operation.

Transfer device and system for an electrophotographic device comprising multiple electrodes

A toner adder roll according to one example embodiment includes an electrically conductive shaft defining an axis of rotation of the toner adder roll. A foam member is cylindrically disposed about the shaft and forms an outer circumferential surface of the toner adder roll. The foam member is composed of a polymeric open-cell foam material. An abrasive agent is dispersed on the outer circumferential surface of the toner adder roll.

Toner adder roll having an abrasive agent additive

An imaging apparatus having a toner transfer station, including a donating member for donating toner forming an image; and a transfer roll which serves to form a transfer nip in which toner is transferred from the donating member to a media sheet disposed in the transfer nip between the donating member and the transfer roll, wherein a product of a resistivity of the transfer nip and a dielectric constant thereof is greater than or equal to a product of a resistivity of the media sheet and a dielectric constant thereof.
