Patent ID: 7532843

Claim:
A paddle for engaging image forming material in a reservoir having an interior surface of irregular geometry, said paddle comprising an axially elongated section radially extending in a single direction from an axis of rotation of said paddle, capable of rotating in said reservoir and having an end face including a component for reaching said interior surface of irregular geometry, said component having a compliant polymeric body section having no openings therein attached to said end face and defined completely in a single first plane that is perpendicular to said axially elongated section having a front opposite said end face, a side and an axially aligned projection extending from said body section and not adjacent any other portion of said body and a formed edge reaching said surface of irregular geometry during rotation of said paddle for removing said image forming material from said surface not reached by said elongated section of said paddle, said formed edge defined completely in a single second plane directly adjoining said first plane, wherein said axially aligned projection and said formed edge are located along said side of the body section and said second plane defined by said formed edge is angled at an angle α between greater than 0 and less than 180 degrees from said front of said body section, wherein said front of said body section is positioned nearest said reservoir surface, wherein said axially aligned projection extends to reach a corresponding surface in said reservoir, in both axial and radial directions of said reservoir and wherein said compliant body section minimizes torque on said paddle as it rotates though said image forming material in said reservoir while allowing said edge to maintain contact with said surface of irregular geometry of said reservoir.
