ABSTRACT:
An electrostatic printer uses a dielectric film (10) as an intermediate recording medium for an electrostatic latent image which is to be printed on a final recording medium (1) such as sheets of paper. The latent image is first developed by inking, and the inked image is then fixed on the final medium by pressure using a transfer unit having pressure rolls (11A, 11B) between which the intermediate medium and the final medium are passed while pressed against each other. Two portions of the same dielectric film are pressed against opposite faces of the final medium as it passes between the pressure rolls of the transfer unit with each portion being suitable for receiving an electrostatic latent image from a corresponding write head (8) with images being inked by corresponding inking devices (9), and with each inking device being associated with a corresponding different one of the rolls of the transfer unit.
