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： A developing unit includes a developing roller including a roller portion. The developing roller is rotatable while carrying a developing liquid on the roller portion. The developing unit also includes a voltage applying device that applies a voltage to the roller portion to form an electric field for development between the roller portion and an image carrier, whereby the developing liquid deposited on the roller portion is transferred to a latent image formed on the image carrier. The roller portion includes a volume resistivity ranging from 0 Ω·cm to 107 Ω·cm.

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.

A developing unit including 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 to develop a latent image formed on the image carrier with the liquid.

When the developer carrier and image carrier are moved away from the developing zone, the toner is moved toward the image over a degree at which the developing liquid can separate at the boundary between the toner layer and the carrier layer.

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： A developing device of the type using a developing liquid and applicable to an image forming apparatus includes a developing roller and a sweep roller. The developing roller is pressed against a photoconductive drum to thereby form a nip. The sweep roller is positioned downstream of the nip in the direction of rotation of the drum and pressed against the drum in such a manner as to sandwich a developed toner layer. The surface of the sweep roller moves at substantially the same speed as the surface of the drum. A bias voltage (250 V) close to the surface potential (100 V to 200 V) of the toner layer formed on the drum is applied to the sweep roller. The bias causes the sweep roller to attract stray excess toner present on the background of the drum after development, thereby preventing a toner image from being blurred.
摘要翻译：使用显影液并适用于图像形成装置的显影装置包括显影辊和清扫辊。将显影辊压在感光鼓上，从而形成辊隙。扫掠辊位于辊隙的下游，沿着滚筒的旋转方向并以压制显影的调色剂层的方式压靠滚筒。扫掠辊的表面以与鼓的表面基本相同的速度移动。接近形成在鼓上的调色剂层的表面电位（100V至200V）的偏置电压（250V）施加到扫掠辊。偏置导致扫掠辊在显影之后吸引存在于滚筒背景上的杂散多余的调色剂，从而防止调色剂图像模糊。
