摘要： A liquid developing method and a liquid developing apparatus that use a highly-concentrated liquid developing agent to develop an electrostatic latent imageA 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 .mu.m thick can be formed on the surface of the developing roller or developing belt (510) 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 (10). 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 .mu.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 .mu.m at a concentration of 5 to 40% is used with a 30 .mu.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 .mu.m.

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： 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.
