摘要： A liquid developer capable of preventing each of the disadvantages of uneven development density caused by uneven distribution of colored particles, poor transfer due to an insufficient amount of the liquid, and poor fixing due to an excess amount of the liquid, without complicating handling with the generation of volatile gas. Present on the surface of toner particles to be dispersed in a carrier liquid made of dimethyl silicone are a silicone group of one-end methacryloxy-modified silicone and a basic group. The silicone group prevents agglutination of the toner particles with each other. The silicone group functions as an affinity group and provides the toner particles with an affinity to the carrier liquid. Thus, it becomes possible to disperse the toner particles uniformly in the carrier liquid. Besides, the basic group on the surface of toner particles allows the toner particles to ensure the desired charge amount. Therefore, colored particles such as the toner particles hardly agglutinate with each other in a nonpolar insulating liquid to be provided as a nonaqueous solvent, while the colored particles can be electrophoresed at high speed by an electric field.
摘要翻译：一种液体显影剂，其能够防止由着色颗粒分布不均匀引起的不均匀显影密度的缺点，由于液体量不足导致的差的转印，以及由于液体过量而导致的不良固定，而不会使产生挥发性气体。存在于分散在由二甲基硅酮制成的载体液体中的调色剂颗粒的表面上的是一端甲基丙烯酰氧基改性的硅氧烷和碱性基团的硅氧烷基团。硅氧烷基防止调色剂颗粒彼此凝集。硅氧烷基团用作亲和基团，并且使载体液体具有亲和性的调色剂颗粒。因此，可以将调色剂颗粒均匀地分散在载体液体中。此外，调色剂颗粒表面上的基本组允许调色剂颗粒确保所需的电荷量。因此，着色颗粒如调色剂颗粒在非极性绝缘液体中难以彼此凝集，作为非水溶剂提供，而着色颗粒可以通过电场高速电泳。

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。

摘要： A liquid developing method that uses a highly-concentrated liquid developing agent to develop an electrostatic latent image. A highly-concentrated liquid developing agent with a viscosity of 100 to 1,000 mPa.s can be used. Therefore, a film of developing agent from 5 to 40 &mgr;m thick can be formed on the surface of the developing roller or developing belt and this provides a soft contact with the photosensitive member surface where the electrostatic latent image has been formed. If the surface of the photosensitive member does not have good release properties, a film of pre-wet liquid can be formed on the surface of the photosensitive member. A gap which is larger than the thickness of the liquid developing agent film and smaller than the sum of the thicknesses of the liquid developing agent film and the pre-wet liquid film is maintained between the surfaces of the photosensitive member and the developing roller or other developing agent bearing member such that the pre-wet liquid is always interposed between the two surfaces. Extremely good copies can be obtained if a 5 to 40 &mgr;m thin film of liquid developing agent with a viscosity of 100 to 10,000 mPa.s and containing toner with an average particle size of 1 to 5.0 &mgr;m at a concentration of 5 to 40% is used with a 30 &mgr;m or less thin film of pre-wet liquid with a viscosity of 0.5 to 5.0 mPa.s and the gap between the photosensitive member and the developing agent roller or other developing agent bearing member is set at 5 to 60 &mgr;m.
