Abstract

A removable unit for an electrophotographic imaging device includes a housing having an opening, a rotatable roll disposed near the opening and adjacent to a bottom of the housing and a blade assembly coupled to the housing. The blade assembly includes a support bracket secured to a wall defining at least a part of the opening of the housing, and a blade member coupled to the support bracket and being positioned in the removable unit so that a distal end portion of the blade member engages with the rotatable roll. The housing, the blade assembly, and a portion of a surface of the rotatable roll define a substantially sealed enclosure for containing toner therein.
