Abstract

In magnetography, magnetic latent images are produced on a magnetic recording medium representing information such as that from an original document. The latent image is developed with magnetic toner particles and transferred in image configuration to a record sheet, such as paper, whereat the developed image is permanently fixed thereto, producing a final hard copy. The magnetic latent image is generally formed by reversing the magnetic polarity of relatively small areas representing picture elements or pixels in a premagnetized DC magnetic field placed on a recording medium such, for example, chromium dioxide. Fringe fields are developed between the opposite magnetic polarities or flux reversals which attract and hold magnetic toner particles.
