Title: Method of manifold copying

Abstract: A method of manifold copying using recording members having a dielectric surface on one side and surface of relatively lower resistivity on the opposite surface, which comprises forming a pack by placing sheet on sheet with the dielectric surfaces facing one way so that each dielectric surface excepting on one outer sheet is in contact with the lower resistivity surface of the next sheet, then placing the pack on a support with the lower resistivity surfaces on each sheet facing the support, then contacting the sheet further removed from the support with pressure imaging means, thereby to form a latent image on each dielectric surface, then separating the sheets of the pack and developing the latent image on each sheet by attracting thereto electroscopic marking particles.
