Electrostatic printing method and device with imaging head containing contact bristles

摘要

The image carrier has a surface (12a) to which electrostatic charges are transferred from the head via contact whiskers (46). The whiskers are of graphite or tungsten protruding from the conductive substrates (44a) of a row of cushions connected by conductive thin films (42) to a control unit (24). A pattern of rows and columns of conductive islands (68) is formed in each pixel region of an anisotropic dielectric layer. Preferably uncharged inks can then be drawn by dipolar forces from the recording surface and transferred to paper.
