摘要： A magnetic brush development roller assembly for an electrographic printer includes a cylindrical multipole magnet mounted for rotation about a cylindrical axis; and a conductive non-magnetic stationary shell surrounding the multipole magnet. The shell defines an axial slot for receiving an imaging head, and has a region of reduced conductance extending substantially around the circumference of the shell, whereby eddy currents generated by rotation of the magnet within the shell and hence resistive heating and drag on the magnet are reduced.

A first ferromagnet is positioned at the first position to maintain the magnetic piston at the first position when current ceases to be applied to the electromagnet in the first direction. A second ferromagnetic is positioned at the second position to maintain the magnetic piston at the second position when current ceases to be applied to the electromagnet in the second direction.
