Abstract: 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.

Abstract: In an image recording apparatus which does not generate ozone and has a simple structure, a pigment supply device where pigment is dispersed in liquid along with a surface active agent contacts with a layer of semiconductor of a photosensitive drum and the semiconductor layer is selectively exposed according to an image to be recorded by a light source. Then the pigment is attached onto the photosensitive drum, and then transferred and fixed onto an image recording paper as an output image. The surface active agent is oxidized by the light source and separated from the pigment to cause selected pigments from the pigment dispersed liquid to attach to the photosensitive drum.

Abstract: This apparatus is disclosed for developing electrostatic latent images, comprising a developer supply unit having a first liquid repellent layer with a thickness in the range of 3 - 400.mu. (preferably 5 - 330.mu.). The first layer is disposed on a surface of a substrate, having a plurality of closely spaced pores distributed uniformly over the entire surface of the substrate and penetrating to the back surface thereof. A liquid developer is supplied to a first or back surface of this unit. A photoconductive sensitive plate is spaced closely to a front or second surface of the developer supply unit, to attract the developer to exude through the pores from the first surface of the said liquid repellent layer. More specifically, an electrostatic voltage is applied between the developer supply unit and the photoconductive sensitive plate to provide an electrostatic latent image preformed of electrostatic charges. Alternatively, a latent image could be formed by exposing the plate to light images or by the effect of pre-exposed light images on the said photoconductive sensitive plate.

Abstract: An image forming method and an image forming apparatus achieve a high developing speed and high transferring efficiency. The method forms a latent image on the surface of an image carrier that repels a coloring liquid, attaches an affinity agent (containing fine silica grains) that has affinity for the coloring liquid, onto the latent image with the electrostatic force, and attaches the coloring liquid onto the affinity agent on the latent image, to visualize the latent image. The method efficiently transfers the visualized image having the affinity agent to a recording medium, to provide a fixed image.
