摘要： A technique includes rotating a squeegee roller to regulate a film thickness of ink on a developer roller; and using the developer roller to transfer a portion of the ink from the developer roller to a photoconductive member. The technique includes creating, by an electrode, a potential bias with the developer roller to transfer the ink to the developer roller; and inhibiting flow streaks on the developer roller, where inhibiting the flow streaks includes restricting a flow of ink between the squeegee roller and the electrode.
