Abstract
An electrophotographic printer includes a rotatable photoreceptor adapted to receive dry toner and a rotatable toning member arranged with respect to the photoreceptor to supply toner thereto. A seal includes a complaint contact member and a non-contact member. The contact member is arranged in mechanical contact with the photoreceptor. The non-contact member is spaced apart from the surface of the toning member by a selected non-zero distance, the selected distance being greater than zero. This reduces dusting.
