Electrostatic transfer type liquid electrophotographic printer

摘要

An electrostatic transfer type liquid electrophotographic printer using a photoreceptor web circulating around a continuous path as a photoreceptor medium is provided. The photoreceptor web is charged to a predetermined potential by a main charger and a plurality of latent electrostatic images is sequentially formed thereon by a plurality of laser scanning units (LSUs). A plurality of developer units are arranged in series in the circulation direction of the photoreceptor web, and sequentially develops the plurality of latent electrostatic images into multi-color toner images with inks containing a liquid carrier and charged toner, thereby forming overlapping multi-color toner images on the photoreceptor web. A concentration control unit controls the concentration of the multi-color toner images to be suitable for electrostatic transfer by adjusting the amount of the liquid carrier applied to the overlapping toner images formed on the photoreceptor web.
