摘要： An image forming apparatus configured to use a highly viscous, dense developing liquid including a carrier liquid and toner. The apparatus includes a developing unit with a developer carrier and a coating member for coating the developing liquid on the developer carrier. The developer carrier conveys the liquid to a developing zone where it faces an image carrier to develop a latent image on the image carrier. In the developing zone, the toner is caused to move toward the image by electrophoresis to form a toner layer in which the toner is present in the carrier liquid and a carrier layer in which the toner is absent. When the developer carrier and image carrier are moved from each other, the toner moves toward the image such that the developing liquid separates at the boundary between the toner and carrier layers.

摘要： An image forming apparatus of the type depositing a developing liquid on a developing sleeve in the form of a thin layer, developing a latent image formed on a photoconductive element with the liquid and transferring the resulting toner image to a recording medium is disclosed. The developing sleeve is implemented as a conductive hollow tubular member. A drive roller is rotatably disposed in the bore of the developing sleeve and extends in the axial direction of the sleeve. A cleaning blade is pressed against the outer periphery of the sleeve for pressing the drive roller via the sleeve. The drive roller and cleaning blade cooperate to cause the sleeve to rotate. An applicator roller applies the liquid to the outer periphery of the sleeve. An electric field for development is formed in a developing region between the photoconductive drum and the sleeve. The liquid is transferred from the sleeve to the latent image formed on the drum for thereby developing it.

摘要： An excess toner removal area is made broader over the whole area with respect to a developer applied area that is broader than an image effective area. Thereby a liquid developer, that tends to spread slightly broader than the applied area after being applied to a photoreceptor drum, is removed by a sweep roller that can sweep excess toner present in an area broader than the original applied area and an excess toner remaining area is then prevented from being formed on the photoreceptor drum. Accordingly, the excess toner on the latent image carrier is removed as much as possible, and a transfer medium and peripheral members are prevented from being soiled due to residual excess toner.

摘要： An image forming apparatus and a developing device that can deposit a developing liquid on a liquid carrier in a form of a thin layer, causing the thin layer to contact an image carrier of the image forming apparatus. A liquid carrier is in contact with the image carrier to carry the thin layer of the developing liquid to the image carrier. A thin layer contact member contacts the thin layer formed on the liquid carrier at a position upstream of where the liquid carrier and the image carrier contact each other in a direction in which the liquid carrier is movable, to apply a shearing force to the thin layer. Further, the thin layer contact member includes a rotary member with a movable surface that rotates, at a position where the rotary member faces the liquid carrier, in a rotating direction opposite to the rotation direction in which the liquid carrier is movable.

摘要： A fixing apparatus causes a softener to adhere to a toner image and then fixes the toner image onto a recording body. The toner image is formed using a liquid developer comprising a toner and carrier solution. The fixing apparatus comprises a fixing roller as a softener feeding device for feeding a fixer containing a softener to a transfer paper which is a recording body, and a pressurizing roller as a pressurizing device for pressurizing the transfer paper at a fixing nip which is a softener feeding position to which the fixer is fed. As the softener contained in the fixer, the one having an affinity for the carrier solution is used.
