摘要： A tandem image forming device for an image forming apparatus of the present invention includes a plurality of image forming means arranged side by side along an intermediate image transfer belt. The image forming means each include a developing device and a cleaning device arranged around an image carrier. One of nearby image forming means has its cleaning device positioned above the developing device of the other image forming means, e.g., an agitating section forming part of the image forming means. This configuration insures smooth circulation of a developer and therefore obviates an irregular developer distribution while reducing the overall size of the image forming device.

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： A wet-type image forming apparatus produces a high-quality toner image by condensing a toner image on a photosensitive drum and adhering the toner image onto the photosensitive drum without contacting a liquid carrier applied on the photosensitive drum. The photosensitive drum carries a latent image formed thereon. The toner image is formed by developing the latent image by using a developing liquid including the liquid carrier and toner dispersed in the liquid carrier. An excessive amount of liquid carrier on the photosensitive drum is removed after the toner image is formed. An electric field is formed which causes a current to flow between an electrically conductive member and the photosensitive drum. An air gap is formed between the liquid carrier on the photosensitive drum and the electrically conductive member so that the current flows through the gap, the liquid carrier and the toner image. The toner image on the photosensitive drum is transferred to a transfer material after the toner image passes an area in which the electric field is generated.

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 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.
