Abstract
The present disclosure relates to an image forming device component that includes an elastomeric material having a surface and a triboelectric charging material that may be exposed on the elastomeric material surface. The triboelectric material may be exposed by a finishing process that results in removal of a portion of the material leaving voids in the surface. The surface may have a surface roughness in the range of about 0.1 to 5.0 Ra. The component may include a developer roller in an electrophotograhic printer and may provide contact electrification to a given toner during a printing operation.
