Abstract:
1. An electrostatic transfer type liquid electrophotographic printer comprising: a continuous photoreceptor web having a charged surface and an opposing back surface, wherein the photoreceptor web rotates around a printing path; at least one exposing unit for selectively discharging the charged surface of the photoreceptor web to form a latent electrostatic image; at least one development unit for developing the latent electrostatic image on the photoreceptor web into a toner image with an ink containing a liquid carrier and charged toner particles, wherein the at least one development unit comprises a developer roller, a toner removal roller, and a squeeze roller, and at least one of the developer roller, the toner removal roller, and the squeeze roller have a corresponding backup roller adjacent to the back surface of the photoreceptor web, and wherein the photoreceptor web is arranged to provide at least 1 degree of contact wrap around the at least one backup roller; and an electrostatic transfer unit for transferring the toner image formed by the at least one development unit from the photoreceptor web to a print medium by electrostatic force.
