Abstract

A xerographic process for preparing a magnetographic master using magnetic dry or liquid toner is disclosed. As shown in the Figures 1 through 5, a conventional photoreceptor device 1 is charged 2 and imaged 3 to form a latent charged image 4 which is developed with toner 5, and fused to form fixed magnetic image 6. The fixed magnetic image 6 on the photoreceptor is suitable as a magnetographic master for subsequent magnetic development 7. The magnetic developer contains magnetic material such as iron oxide or various nickel magnetic alloys. To produce reproductions, the fixed master 6 is developed by conventional magnetographic processing using magnetic toner. The developed magnetic image 7 is transferred to paper and fused in a conventional manner.
