Title: Magnetic brush for use in magnetic printing

Abstract: An improved magnetic brush for transferring toner to a latent image in a magnetic printing machine comprises a rotatable applicator cylinder disposed around a multipole magnetic stator. The two poles of the stator lying closest to the image are excited with magnetic fields of like polarity to minimize interaction between the magnetic brush field and the recorded magnetic image.
