ABSTRACT:
A process for reproducing graphic information wherein a magnetic image is formed in a premagnetized layer of acicular chromium dioxide by heating the chromium dioxide selectively to above its Curie point. Ferromagnetic toner particles are then applied uniformly to the chromium dioxide layer, so as to adhere only in the magnetized areas. The toner particles are electrostatically transferred to a substrate and fused into position. Alternating current coronas or other static neutralizing devices are used to neutralize unwanted charges on toner particles which would otherwise cause fuzzy images and unwanted background markings on the final copies.
