A carrier bead pickoff device is provided for removing ferromagnetic
carrier beads from a developed image-carrying surface of a moving
photoreceptor in an electrostatographic image reproduction machine. The
carrier bead pickoff device includes (a) an elongate stationary core
having a first elongate segment, and a second elongate segment, the
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
the 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 the smooth outer surface (i)
for rotation with the portion, (ii) for temporary magnetization when
rotating through the concentrated magnetic field within the pickoff
region, and (iii) for contacting and retaining ferromagnetic carrier
beads, attracted by the primary magnetic member towards the smooth outer
surface, during rotation of the portion of the smooth outer surface
through the pickoff region.
