Patent ID: 7142798

Claim:
A carrier bead pickoff device for removing ferromagnetic cater beads from a developed image-carrying surface of a moving photoreceptor in an electrostatographic image reproduction machine, the carrier bead pickoff device comprising: (a) an elongate stationary core having a first elongate segment, and a second elongate segment, said second elongate segment including a primary magnetic member for generating a concentrated magnetic field within a pickoff region locatable proximate the developed image-carrying surface; (b) a rotatable, non-ferromagnetic cylindrical shell mounted co-axially over said elongate stationary core and having a first end, a second end, and a shell wall having a smooth outer surface; and (c) at least one elongate ferromagnetic strip formed over a portion of said smooth outer surface (i) for rotation with said portion, (ii) for temporary magnetization when rotating through said concentrated magnetic field within said pickoff region, and (iii) for contacting and retaining ferromagnetic carrier beads, attracted by said primary magnetic member towards said smooth outer surface, during rotation of said portion of said smooth outer surface through said pickoff region.
