    • 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.
    • 湿式图像形成装置通过将感光鼓上的调色剂图像聚焦并将调色剂图像粘附到感光鼓上而不接触施加在感光鼓上的液体载体而产生高质量的调色剂图像。 感光鼓承载形成在其上的潜像。 通过使用包括液体载体的显影液和分散在液体载体中的调色剂显影潜像来形成调色剂图像。 在形成调色剂图像之后,去除感光鼓上的过量液体载体。 形成电场,其导致电流在导电构件和感光鼓之间流动。 在感光鼓上的液体载体和导电构件之间形成气隙,使得电流流过间隙,液体载体和调色剂图像。 在调色剂图像通过其中产生电场的区域之后,将感光鼓上的调色剂图像转印到转印材料上。

    • 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.
    • 一种图像形成装置,被配置为使用由载体液体和调色剂组成的高粘度,致密的显影液。 该装置包括具有显影剂载体的显影单元和用于将显影液涂覆在显影剂载体上的涂层部件。 显影剂载体将液体输送到显影区域,在显影区域中,其面向图像载体以在图像载体上显影潜像。 在显影区域中,使调色剂通过电泳向图像移动,形成调色剂存在于载体液体中的调色剂层和不存在调色剂的载体层。 当显影剂载体和图像载体彼此移动时,调色剂朝向图像移动,使得显影液体在调色剂和载体层之间的边界处分离。
