ABSTRACT:
A doctor blade (1) has an outer metal surface (15) on a grit layer with flexible backing. The blade is pushed by foam (21) or, alternately by inherent resilience, onto a developer roller (7). The compliance reduces toner variations which result from surface variations of the blade and the roller.
