Abstract
An apparatus for developing a latent magnetic image on a moving magnetic recording medium in which the image is always satisfactorily developed without excess toner particles yet using a simple mechanism. A developing magnet extends parallel to the surface of the recording medium, which is in the form of a magnetic drum. The direction of the magnetic field produced by the magnet at the point (line) of closest approach of the recording medium and magnet is the same as the direction of the magnetic field at boundaries between background regions and recorded image regions on the magnetic recording medium. A nonmagnetic rotating sleeve is positioned around the development magnet, and magnetic toner supplied to the outer surface of the sleeve.
