Abstract: Disclosed herein is a method for electrostatic printing, wherein the method comprises (a) providing an ink composition comprising particles comprising a resin, wherein the ink composition contains less than 0.3 mg of charge director per g of solids in the ink composition; (b) passing the ink composition between a first electrode and a developer roller, wherein sufficient potential is applied between the developer roller and the electrode such that the resin particles are charged and adhere to the developer roller; (c) transferring at least some of the particles from the developer roller to a photoimaging plate to form an image on the photoimaging plate; and (d) transferring the image from the photoimaging plate to a print medium. Also disclosed here is an apparatus for carrying out the method, and a print medium printed using the method.

Abstract: Apparatus is described which, in use, applies a thin film of a wetting agent, such as water or a water-based solution, onto paper or other print medium before applying a liquid toner. The wetting agent is applied at a predetermined distance from an image transfer area. The wetting agent acts to promote adhesion of the liquid toner to the print medium. The adhesion of the liquid toner to the print medium is further improved by supplying the wetting agent at a temperature higher than room temperature.

Abstract: In some examples, an image forming apparatus includes a photoconductive member to move in a rotational direction, a charging unit to charge the photoconductive member, a discharging unit to discharge a portion of the photoconductive member to form a latent image thereon, and a plurality of ink applicator units to sequentially apply a plurality of ink layers, respectively, toward the latent image to form an ink image. The image forming apparatus may also include an image transfer blanket to receive the ink image including the plurality of ink layers from the photoconductive member.

Abstract: In an example, an apparatus is described that includes a photosensitive imaging plate, an intermediate transfer member, and a heating unit. The photosensitive imaging plate attracts a layer of printing fluid. The intermediate transfer member contacts the photosensitive imaging plate and receives the layer of printing fluid from the photosensitive imaging plate. The heating unit includes an array of individually addressable heating elements and heats the intermediate transfer member in a manner that is spatially selective along two axes: a first axis in a direction of a width of the intermediate transfer member and a second axis in a direction of a rotation of the intermediate transfer member.
