Zusammenfassung:A doctor blade assembly for the developer unit of an electrophotographic imaging system. The doctor blade assembly includes a blade member having a first longitudinal edge for contacting a developer roll of an imaging system; a bracket member operatively connected to the blade member; and at least one bias member having a first end portion along a first longitudinal end portion of the bracket member and a second end portion contacting a distal portion of the blade member so as to present a force thereon. The force presented by the bias member serves as a counterforce to at least partly offset a force presented on the doctor blade and developer roll by a seal member of the developer unit.
