摘要： 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.

摘要： A roll for use in an electrophotographic image forming device according to one example embodiment includes a shaft defining an axis of rotation of the roll. The roll includes an outer circumferential surface having a pair of axial ends. Recessed grooves and/or raised ribs are present in the outer circumferential surface near the axial ends. The recessed grooves and/or raised ribs are angled relative to the axis of rotation of the roll away from a direction of rotation of the roll from the axial ends inward or parallel to the axis of rotation of the roll to direct toner away from the axial ends.

摘要： An endless electrophotographic member, such as a developer roller, which indicates an improved resistance to nip banding. The improvement to nip banding may be provided by the use of an organic salt within a roller surface region. The roller may provide, at a nip location, a resistive surface layer having an electrical resistance that avoids the development of nip banding and relatively dark regions on printed media.
