摘要： An electrostatic image of graphical information is formed on a surface, for example that of an endless tape, a drum or suitable paper, and then magnetic toner particles are applied to the surface and adhere thereto in correspondence with the electrostatic image. Portions of the same surface, in the case of the tape, or of another surface, when the drum or paper are employed, are magnetized, as determined by the location of the toner prticles, to form a magnetic image corresponding to the electrostatic image. Then the toner medium are transferred by friction to a copy mdium such as ordinary paper, while the magnetic image is retained or stored on the surface. Toner particles then again can be applied to the magnetic image for production of additional copies. In other embodiments, magnetic material located on a surface in correspondence with graphical information, such as a hard copy comprising magnetic toner particles fixed to a paper substrate, is utilized in magnetizing a surface such as that of a drum or an endless tape, to form a magnetic image of the graphical information. The magnetic image can have toner particles applied thereto for photocopying by transfer to a copy medium such as paper, or it can be scanned to generate a sequential electrical signal indicative of the graphical information which signal is compatible with computer forms of storage and processing.
