Abstract: The present application relates to a method for concentrating an ink for an electrostatic printing process, wherein the method comprises the steps of: (a) providing the ink for an electrostatic printing process, the ink comprising chargeable particles in a liquid carrier; (b) passing the ink between a chargeable conveyor and a first electrode, wherein a potential is applied such that the ink becomes adhered to the chargeable conveyor; (c) passing the ink on the conveyor past a moving surface, wherein the ink contacts the moving surface and a potential is applied between the conveyor and the moving surface, such that the chargeable particles are disposed to move toward the conveyor and some of the liquid carrier is removed to increase the concentration of the chargeable particles in the liquid carrier on the conveyor to form a concentrated ink on the conveyor, the conveyor and the moving surface then diverging from one another, such that substantially all of the concentrated ink remains on the conveyor; (d)

Abstract: This invention is related to a liquid developer dispersion for use in a digital printing apparatus comprising a non volatile carrier liquid, a marking particle and a dispersing compounds, wherein the marking particle in the liquid developer dispersion is stabilized during storage and wherein at fusing two phases are formed. The invention is also related to the use of the developer in a digital printing apparatus and to a method for preparing the liquid developer dispersion.

Abstract: An image forming apparatus employing nonvolatile liquid developers is provided, which image forming apparatus exhibits high transfer efficiency in transferring images on an image carrier to a recording media and enables formation of images with sufficient fixing strength. An image forming apparatus which incorporates a squeezing mechanism which removes a part of carrier liquid from the liquid developer incorporating image visualizing particles, fine thermoplastic resin particles, and nonvolatile carrier liquid, and incorporates a transferring mechanism which transfers a visible image, in which a part of carrier liquid is removed, onto the recording medium.

Abstract: A liquid developer collection apparatus and an image forming apparatus can prevent image disturbances and also disturbances of the toner particles on the image section that can be produced by squeezing. The liquid developer collection apparatus includes a first squeezing section 113aY that squeeze a liquid developer on an image carrier carrying an image developed by the liquid developer containing carrier liquid and toner particles, and a second squeezing section 113bY arranged vertically above the first squeezing section 113aY to squeeze the image carrier squeezed by the first squeezing section 113aY, and the liquid developer collected by the second squeezing section 113bY is made to fall free onto the first squeezing section 113aY and collected.

Abstract: There are described methods and apparatus for assessing foams generated from liquids. Existing methods are slow and labor intensive. The new methods involve generating foams from liquids and optically obtaining information to enable parameters relating to the generated foam to be measured. Although single samples of liquids may be processed the methods are particularly suited to processing multiple samples to obtain data relating to foams at a high rate. The apparatus includes automated handling equipment to enable samples to be moved between workstations and relative to associated optical equipment that is used to obtain information relating to the foams.
