Abstract
A development device includes components such as a housing, a magnetic roll in the housing that moves marking material in the housing, a donor roll in the housing that is positioned to receive the marking material from the magnetic roll, a manifold in the housing, etc. The manifold has a manifold opening positioned to create airflow from the surface of the donor roll. Further, such structures include a seal over the manifold opening. The seal is a component that has a planar linear surface with seal openings that are aligned with the manifold opening. The edge of the housing adjacent the manifold opening is a first distance from the magnetic roll and the edge of the seal is a second, closer distance from the magnetic roll.
