Abstract:
A liquid electrophotographic printer comprising:a photoreceptor web circulating around a continuous path, having a non-image region charged by a main charger to a first potential and an image region in which a latent electrostatic image is formed by a laser scanning unit to have a second potential, wherein the second potential is lower than the first potential; a development unit for developing the latent electrostatic image using an ink in which toner particles of a predetermined color are dispersed in a liquid carrier; a drying unit for drying a developed toner image; and a transfer unit for transferring a dried image to a print paper, wherein the development unit comprises: a developer roller rotatably installed with a predetermined separation gap from the photoreceptor web, for forming the toner image by attaching the toner particles of the ink to the image region; a toner removal roller rotatably installed with a predetermined separation gap from the photoreceptor web, for removing toner particles remaining in a liquid carrier film adhering to the non-image region by moving said toner particles toward said toner removal roller; and a squeeze roller rotatably installed in contact with the photoreceptor web, for squeezing the liquid carrier out of the toner image by compressing the toner image, and wherein a surface of the squeeze roller is charged to a fifth potential in the range of 900-1300 volts to charge the photoreceptor web.
