MAGNETOGRAPHIC IMAGING MEMBER AND THE METHOD OF ITS USE

摘要

A magnetographic imaging member is provided which includes a photoconductive layer sandwiched between a transparent conductive substrate and an overcoating of magnetic particles dispersed in a dielectric material. A magnetic latent image is formed in the member by first producing an electrostatic latent image on the premagnetized dielectric coating and developing it with a thermal radiation reflective toner. The surface is then subjected to thermal radiation which demagnetizes the pigment in the overcoating by raising it to a temperature above its Curie point except in the areas where the developed electrostatic image reflects the heat. The latent magnetic image can be repetitively developed with magnetic toner.
