Developer Unit Architecture for an Imaging Device

A removable unit for an electrophotographic imaging device, comprising:

• a housing for containing toner and being formed with an opening that extends along a width of the housing;
• a rotatable roll disposed near the opening and adjacent to a bottom wall of the housing;
• and
• a blade assembly coupled to the housing, comprising a support bracket secured along the opening of the housing, a blade member coupled to the support bracket and being positioned so that a distal end of the blade member engages with the rotatable roll;
• wherein contact between the blade member and the roll causes a lower portion of the blade member to bend away from a lower portion of the support bracket.

A blade assembly for an imaging system, comprising:

• a blade member having a first surface and a longitudinal width defined between a first end and a second end;
• and
• a bracket member having a having a first surface, the bracket member and the blade member being attached together such that the first surface of the blade member is adjacent the first surface of the bracket member;
• wherein the blade member has a width between a first end and a second end thereof and a cantilever length which is different near the first and second ends than a location near a central portion of the blade member, the cantilever length of the blade member being a distance between an attachment point of the blade member to the support bracket and the distal end of the blade member.
