PROCESS FOR MAGNETICALLY TRANSFERRING A POWDER IMAGE

摘要

Process for transferring a powder image which has been formed with permanently magnetizable developing powder, which process comprises the steps of magnetically transferring the powder image (2) to an intermediate receiving member (4) having a uniform magnetic permeability over its whole surface and comprising magnetizable material having no remanent magnetism and subsequently transferring the powder image from the intermediate receiving material (9). The transfer of the powder image (2) to the intermediate receiving member (4) is effected by magnetizing the powder image (2) and contacting it with the intermediate receiving member (4). In a specific embodiment of the invention, the powder image (2) is magnetized while it is in contact with the surface of the intermediate receiving member (4). The intermediate receiving member (4) preferably has a relative magnetic permeability of at least 2.
