摘要： An apparatus for developing an electrostatic latent image formed on a photosensitive member (10) by a toner. The developing apparatus includes a pre-wet device (20) for applying a pre-wet solution to the photosensitive member (10), and a developing device (20) for uniformly coating the latent image surface of the photosensitive member (10) with a high-viscosity liquid developer (508), which is a high-density suspension of toner in an insulating liquid and is carried onto the latent image in the form of film that is spread to a regulated thickness of 5-40 mu m on a belt (510) by a feeder (504). According to the apparatus, a small amount of the liquid developer can be supplied uniformly to the latent image surface of an image support. The developer feeder (504) may be a layer formation blade so disposed as to come into contact with the developing belt or at least two rollers or a circular cylinder coated with a thin sponge layer.

摘要： A method and an apparatus for developing an electrostatic latent image by using a liquid developer in a high concentration. In order to make usable a high concentration liquid developer having a viscosity of 100 to 10,000 mPa.s, a developer layer having a thickness of 5 to 40 mu m is formed on the surface of a developing roller or a developing belt (510) and is brought into gentle contact with the surface of a photosensitive member on which an electrostatic latent image is formed. When mold releasability on the surface of the photosensitive member is not satisfactory, a pre-wet liquid film is formed on the surface of the photosensitive member (10), and the gap between the photosensitive member and the surface of the developing roller, etc, is kept at a gap which is greater than the thickness of the film of the liquid developer but is smaller than the sum of the film thickness of the liquid developer and the film thickness of the pre-wet liquid film so that the pre-wet liquid always exists between both surfaces. A pre-wet liquid having a viscosity of 0.5 to 5.0 mPa.s and a film thickness of not greater than 30 mu m is used for the developer film of the liquid developer containing a toner having a mean particle size of 0.1 to 5.0 mu m in a concentration of 5 to 40 %, and having a viscosity of 100 to 10,000 mPa.s and a thickness of 5 to 40 mu m, and the gap between the photosensitive member and the developing roller, etc, is kept between 5 and 60 mu m. In this way, an extremely satisfactory copy can be obtained.
摘要翻译：通过使用高浓度的液体显影剂显影静电潜像的方法和装置。为了使粘度为100〜10,000mPa.s的高浓度液体显影剂成为可用，在显影辊或显影带（510）的表面上形成厚度为5〜40μm的显影剂层，与形成有静电潜像的感光构件的表面温和接触。当感光构件表面上的脱模性不理想时，在感光构件（10）的表面上形成预湿液膜，并且感光构件与显影辊的表面之间的间隙等，保持在比液体显影剂的膜厚大的间隙，但是比液体显影剂的膜厚和预湿液膜的膜厚之和小，因此预湿液体总是存在于两个表面之间。对于含有平均粒径为0.1〜5.0μm的调色剂的液体显影剂的显影剂膜，使用粘度为0.5〜5.0mPa.s，膜厚为30μm以下的预湿液浓度为5〜40％，粘度为100〜10,000mPa.s，厚度为5〜40μm，感光体与显影辊之间的间隙等保持在5〜60之间亩以这种方式，可以获得非常令人满意的复印。
