Electrostatic transfer printing

摘要

Electrostatic transfer printing in which a latent electrostatic image is formed on a cylindrical dielectrical member by means of a glow discharge ion source. The image is then toned and pressure-transferred to a receptor, such as a sheet of paper, which is passed between the cylindrical dielectric member and a transfer roller. Scraper blades may be included to remove residual toner from the cylindrical dielectric member and the transfer roller. Means may also be included to erase any latent residual electrostatic image on the cylindrical dielectric member.
