发明名称 Process for magnetically transferring a powder image.
摘要 Process for transferring a powder image (2) which has been formed with magnetically attractable developing powder, which process comprises the steps of magnetically transferring the powder image (2) to an intermediate receiving member (4) comprising zones of a first material, separated from each other by a second material, in which either the first or the second material is magnetizable and the other material is non-magnetizable, and subsequently transferring the powder image (2) from the intermediate receiving member (4) to a final receiving material (9). The magnetizable material present on the intermediate receiving member (4) may be a material having no remanent magnetism, but in a preferred embodiment thin material has a remanent magnetism of at least 2 kA/m. Transfer of the powder image (2) to the intermediate receiving member (4) is effected by magnetizing the powder image (2) or the magnetizable zones of the intermediate receiving member (4) and contacting the powder image (2) with the receiving member (4).
