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.

摘要： Electrographic printing apparatus for forming a toner image on a recording medium, includes a magnetic brush having a rotatable magnetic core and a stationary outer shell. A developer supply supplies a magnetic developer powder including toner to the magnetic brush. A print head is located on the outer shell of the magnetic brush. The print head includes microchannels or magnetic strips for forming a plurality of parallel lines of developer, and transfer electrodes for selectively transferring toner from two or more locations within each line to a receiver moving relative to the print head. The parallel lines of developer are arranged at an angle with respect to the direction of movement of the receiver, thereby effectively increasing the resolution of the print head in a direction perpendicular to the movement of the receiver. A receiver electrode is arranged in spaced relation to the transfer electrodes to define a recording region through which the receiver is moved.
