摘要： An image forming apparatus and a developing device that can deposit a developing liquid on a liquid carrier in a form of a thin layer, causing the thin layer to contact an image carrier of the image forming apparatus. A liquid carrier is in contact with the image carrier to carry the thin layer of the developing liquid to the image carrier. A thin layer contact member contacts the thin layer formed on the liquid carrier at a position upstream of where the liquid carrier and the image carrier contact each other in a direction in which the liquid carrier is movable, to apply a shearing force to the thin layer. Further, the thin layer contact member includes a rotary member with a movable surface that rotates, at a position where the rotary member faces the liquid carrier, in a rotating direction opposite to the rotation direction in which the liquid carrier is movable.

摘要： An image forming apparatus, a developing device and a program recording medium capable of reducing short image density, background contamination and short image sharpness ascribable to the use of a developing liquid whose viscosity characteristic is dependent on a shearing force. Before an applicator roller included in a developing device starts rotating for developing a latent image formed on a photoconductive drum, screws disposed in a liquid storing portion start rotating.

摘要： In an image forming apparatus, a developing device includes a reservoir storing a viscous and dense developing liquid. A developing sleeve, an applicator roller, a circulation pump for circulating the liquid and a screw for agitating the liquid are disposed in the reservoir. The reservoir is open only at its portion where the developing sleeve contacts an image carrier. The liquid is agitated by the screw before flowing into the circulation pump and then applied to the applicator roller. As a result, the liquid is fed to the developing sleeve via the applicator roller with a uniform toner content. The apparatus is small size and stably forms high quality images.

摘要： An image forming apparatus configured to use a highly viscous, dense developing liquid including 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： 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： 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.
