摘要：
A magnetic member in which the magnetic portion thereof is magnetized to saturation impressing a plurality of magnetic poles thereon. At least one non-magnetic portion is integral with the magnetic portion so that the volume of magnetic material within the magnetic member varies producing a magnetic field having a preselected intensity profile. The magnetic member may be utilized in a development system or cleaning system of an electrophotographic printing machine.
