ABSTRACT:
An electrostatic transfer type liquid electrophotographic printer which has a photoreceptor web having a charged surface and opposing back surface, at least one exposing unit for forming a latent electrostatic image onto the charged surface of the photoreceptor web, and at least one development unit for developing the latent electrostatic image on the photoreceptor web into a toner image, wherein each development unit has a developer roller, a toner removal roller, and a squeeze roller, and a backup roller corresponding to at least one of the developer roller, toner removal roller, and squeeze roller, and wherein the photoreceptor web is arranged to provide at least 1 degree of contact wrap around at least one of the backup rollers. The printer further includes an electrostatic transfer unit for transferring the toner images formed in each development unit from the photoreceptor web to a print medium by electrostatic force.
