Abstract
An imaging system is provided whereby graphic information from a source is magnetically recorded on a receiving surface. The imaging system comprises an arrangement for shaping a magnetic field to substantially linear configuration. A photo-responsive element is provided for varying the intensity of the magnetic field along the line in accordance with information contained in a corresponding line of the source of the original graphic information. An intermediary receiving surface is provided to receive the magnetic information and construct a magnetic image thereon. A toner supply is also provided in magnetically attractable relationship to the intermediary receiving surface for causing transfer of toner material from the supply to the intermediary receiving surface in a quantity corresponding to the variations of the magnetic field intensity on the intermediary receiving surface. Elements are also provided to transfer the toner image to a writing or final receiving surface where it is fixed to provide a graphic record of the original source material.
