The magnets for a magnetic brush used to apply toner to a photoreceptor surface carrying an electrostatic latent image, are in the form of strips of magnetic material formed separately from a holder for them. In order to arrive at the desired magnetic polar diagram for the magnetic brush, the magnets need to be of different strengths and to be positioned around the periphery of the holder. The different strengths are obtained by using bars of magnetic material of different cross-sectional areas.
