摘要： A wet process image forming apparatus using a developing liquid consisting of a carrier liquid and a toner dispersed therein, in which air containing carrier vapor produced in, e.g., a fixing section, is sucked by a suction fan via a first duct into a liquefying section. The liquefying section liquefies the carrier vapor and water vapor. A separating section is disposed below the liquefying portion and includes a receptacle. A liquid produced by the liquefying section is caused to flow down into the receptacle along a chain due to its own weight. The separating section separates the liquid into the carrier liquid and water on the basis of a difference in specific gravity. Only the carrier overlying the water in the receptacle is fed to a carrier tank via overflow ports formed in the wall of the receptacle. The water is delivered to a water tank via a pipe. The pipe is so configured as to maintain the liquid level in the receptacle substantially at the level of the overflow ports.

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.

摘要翻译： 相对于比图像有效区域更宽的显影剂施加区域，在整个区域上使多余的调色剂移除区域变得更宽。 因此，在施加到感光鼓之后，倾向于比施加的区域稍微扩展的液体显影剂通过吹扫辊去除，该吹扫辊可以清除存在于比原始涂覆区域宽的区域中的多余的调色剂和多余的调色剂剩余面积 然后防止形成在感光鼓上。 因此，尽可能地去除潜像载体上的多余的调色剂，并且防止转印介质和周边部件由于剩余的多余调色剂而变脏。

摘要： An image forming apparatus configured to use a highly viscous, dense developing liquid consisting of 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： A removal nip having a predetermined width is formed by a sweep roller pressurizing mechanism, which adjusts the length of a tension spring by rotating an adjustment screw, and adjusting the size of an energizing force of a sweep roller with respect to a photosensitive drum. A pressurizing mechanism similar to the sweep roller pressurizing mechanism is also provided in a developing roller, to adjust the energizing force of the developing roller, to thereby form a developing nip having a predetermined width.

摘要： An image forming apparatus of the present invention uses a highly viscous, dense developing liquid consisting of a carrier liquid and toner dispersed therein. A developing unit includes 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 thereby develop a latent image formed on the image carrier with the liquid. In the developing zone, the toner in the liquid, which faces the image of the image carrier, is caused to move toward the image by electrophoresis to thereby form a toner layer in which the toner is present in the carrier liquid and a carrier layer in which the toner is absent in the same. When the developer carrier and image carrier moved away from the developing zone part from each other, the toner is caused to move toward the image over a degree at which the developing liquid can separate at the boundary between the toner layer and the carrier layer.
