摘要： A liquid-development electrophotographic apparatus utilizes a nonvolatile, high-viscosity, high-concentration liquid toner as a liquid developer. A developing section is in contact with photosensitive drums 11-14, on which an electrostatic latent image is formed, so that the liquid developer is supplied onto photosensitive drums 11-14. Toner particles contained in the liquid developer adhere to the photosensitive drums 11-14 according to an electric field established between the developing section and the photosensitive drums 11-14 to form toner images. The toner images are transferred from the photosensitive drums 11-14 to an intermediate transfer section. A transfer-and-fixation section includes a heater to melt-transfer the toner images onto the printing medium. A development section is disposed at a lower portion of the apparatus to prevent smudging of the printing medium and the intermediate transfer section even when the liquid toner spills.

摘要： Provided are an applicator roller for conveying and applying liquid toner onto a developing roller in the form of a level, thin layer, and a conductive blade which comes into contact with a liquid toner layer on the developing roller. A predetermined amount of liquid toner passes through a gap between the conductive blade and the developer roller; and voltage is applied to the conductive blade so as to establish a state such that toner particles contained in the liquid toner are sparsely scattered in a surface region of a level, thin toner layer on the developing roller. Subsequently, the liquid toner, whose surface region is in a state such that toner particles are sparsely scattered, is brought into contact with an image bearer body for performing development.

摘要： A toner image is transferred from a photosensitive member 10 onto an intermediate transfer belt 24. Toner particles transferred onto the intermediate transfer belt 24 are melted through application of heat, and the molten toner is transferred onto a printing medium. A carrier-removing roller 29 is disposed downstream of a position where a toner layer on the intermediate transfer belt 24 is melted through application of heat. Through utilization of a phenomenon that toner particles (resin component) are melted and integrated in a heating process and a phenomenon that the carrier solvent (liquid component) is isolated in the heating process, the carrier solvent is removed efficiently. Also, there is disposed at the position of the heating process a carrier-removing roller 28 for removing the carrier solvent from the intermediate transfer belt 24 while the toner layer on the intermediate transfer belt 24 is being melted through application of heat.

摘要： A full-color electrophotographic apparatus of the present invention is configured such that a toner image is formed on an intermediate transfer member. The intermediate transfer member is heated to a temperature equal to or higher than the softening start temperature of resin contained in a liquid toner and equal to or lower than the withstand temperature of a photoconductor member. A carrier-removing roller to which bias can be applied abuts the intermediate transfer member so as to remove a carrier while packing softened toner by the force of an electric field induced by bias. In a transfer section for transfer to a printing medium, a backup roller presses the printing medium against the intermediate transfer member, and the toner image is transferred from the intermediate transfer member to the printing medium. Before being pressed against the toner image on the intermediate transfer member, the printing medium is heated. Bias is applied to the backup roller such that the toner image on the intermediate transfer is attracted toward the printing medium by the action of an electric field, thereby assisting transfer. By so doing, the intermediate transfer member does not need to undergo cooling before coming into contact with the photoconductor member, thereby avoiding occurrence of thermal damage to the photoconductor member.

摘要： In the present invention, a toner image produced through a development process of supplying a liquid toner onto an image bearing body bearing an electrostatic latent image is transferred from the image bearing body onto an intermediate transfer body and then transferred from the intermediate transfer body onto a printing medium by use of a backup roller in a transfer-and-fixation zone. The printing medium is preheated to a temperature required for transfer and fixation before the printing medium reaches the transfer-and-fixation zone. No heating means is provided in the transfer-and-fixation zone, and the intermediate transfer body and the backup roller are pressed against each other at a high pressure ranging from 10 kg/cm2 to 60 kg/cm2. Alternatively, the intermediate transfer body is provided with heating means; resin for use in the liquid toner has a softening temperature not higher than withstand temperatures of members other than the intermediate transfer body such as a photosensitive drum; and the intermediate transfer body is heated to a temperature not lower than the softening temperature of the resin and not higher than the withstand temperatures of the other members.

摘要： A liquid-development electrophotographic apparatus forms on a toner-image-bearing body a plurality of color images developed by a plurality of developing units, one for each color, that use liquid toner. One or more carrier-removing units for removing excessive carrier from a toner layer that forms a toner image are disposed downstream of each developing unit and upstream of the next developing unit disposed upstream of the former developing unit with respect to a process progress direction. Each carrier-removing unit includes two or more conductive collection rollers to which a bias voltage is applied in such a direction as to press toner against the toner-image-bearing body and which is brought into contact with the toner-image-bearing body. The upstream roller is rotated in the same direction as the direction of surface movement of the toner-image-bearing body, whereas the downstream roller is rotated in the opposite direction. The result is that influence of carrier on the already transferred image is suppressed, and hence occurrences of irregular transfer of the images and occurrences of disturbance of the already transferred image are minimized.
