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 apparatus which forms a discharge electric field in order to discharge an object. The apparatus includes an electrode member facing and separated by a preselected gap from the object, and a power source which applies a discharge voltage to the electrode member to thereby cause discharge to occur between the object and the electrode member. Further, the electrode member at the gap includes a material selected in association with the gap so that a functional relationship between the discharge voltage and a discharge current caused by the discharge voltage is a continuous function.

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： 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.
