Abstract: An image forming apparatus includes an optical unit which forms an electrostatic latent image on a surface of a photosensitive body, a developing device which supplies a liquid developer on the electrostatic latent image formed by the optical unit, and develops the electrostatic latent image into a develop image, a condensing device which condenses the developer image, and a transfer device which transfers the developer image condensed by the condensing device to a recording medium, while applying a shearing stress to the developer image.

Abstract: A method and an apparatus for printing an image on a print medium with a liquid developer which includes a liquid carrier and a toner dispersed in the liquid carrier. The image is printed by forming a toner image having the toner from the liquid developer, and transferring the toner image to the print medium under pressure. By adjusting a complex viscosity coefficient of the toner forming the toner image to be transferred to a value satisfying the formula: 1×104<&eegr;<1×106, wherein &eegr; represents the complex viscosity coefficient (Pa·s) of the toner, the toner image to be transferred to the print medium is controlled.

Abstract: An image forming apparatus of the present invention having a transferring particle layer forming equipment which forms a transferring particle layer prior to forming a toner layer on a surface of an image recording member, whose coagulation force among the transferring particles in the transferring particle layer is smaller than adhesive force of the transferring particle layer to the image recording member, a development equipment which forms a toner layer on a surface of the image recording member according to image information with a liquid developer in a manner that a part of the toner layer is superimposed on the transferring particle layer and a transfer equipment which transfer the toner layer to a transfer medium together with a part of the transferring particle layer. As a result, high transfer efficiency can be obtained, and an image forming apparatus which realizes high image quality is provided.

Abstract: A liquid developer electrophotographic apparatus and method for developing one or more successive color images on a previous color image formed on a latent image retaining body, wherein peeling off the prior color image is prevented by establishing a reversible electrophoretic transfer efficiency of toner particles in the prior toner image to be not greater than 60% in the liquid developer for the successive color image while applying an electrical potential difference between the latent image retaining body and a developing electrode for the successive developing step(s). A resin content of the toner particles forming the previous color image may be selected to achieve the reversible electrophoretic transfer efficiency of 60% or less.

Abstract: Disclosed is a method and an apparatus for printing an image on a print medium with a liquid developer which comprises a liquid carrier and a toner dispersed in the liquid carrier. The image is printed by forming a toner image comprising the toner from the liquid developer; and transferring the toner image to the print medium under pressure.

Abstract: Method of a liquid process type electrophotographic apparatus forming a multicolor visible image on a surface of a photosensitive drum, which prevents the visible image after the second color from being disturbed. After a visible image of the first color has been formed with a development unit on a surface of a photosensitive drum, a part of liquid carrier existing on the surface of the photosensitive drum is removed by using a squeeze roller and an air blower. When an electrostatic latent image is formed with a charger 1 and an exposing unit on the photosensitive drum where the visible image of the first color has been formed, disturbance of the electrostatic latent image caused by a large amount of liquid carrier or lack of liquid carrier can be reduced by reserving a predetermined very small amount of liquid carrier, and disturbance of a visible image of the second color to be developed by a development unit can be reduced.
