Abstract: PROBLEM TO BE SOLVED: To make obtainable a good dispersed state as well as to make obtainable a good image by dividedly adding an electric charge controlling agent and/or a dispersant in plural steps. SOLUTION: Colored particles consisting essentially of a pigment and a resin are dispersed in a petroleum hydrocarbon as a carrier liq., e.g. by 0.1-20 wt.% to obtain a liq. developer. The average particle diameter of the colored particles is, e.g. 0.3-5 μm, preferably 0.5-3 μm. When the developer is produced, an electric charge controlling agent and/or a dispersant is dividedly added in two or more steps, at the time of comminuting and dispersing the toner particles and at the time of mixing with the developer. The ratio (B/A) of the AC conductivity (B) of a mixture of the electric charge controlling agent and/or the dispersant with the developer to the AC conductivity (A) of only the developer is >=1.5, preferably >=2, further preferably >=3. In the case of B/A

Abstract: PROBLEM TO BE SOLVED: To prevent toner from being attached to a heat roller and to obtain an excellent fixed image even when a fixing is executed by the heat roller by including the specified quantity of silicone oil having the viscosity of a specified value. SOLUTION: The silicone oil whose viscosity at 25 deg.C is >=1 cSt and 50 cSt, the silicone oil is not sufficiently mixed in developer. As the result, it occurs that a droplet-state defect is caused or desired printing density cannot be obtained because developing density is lowered when an electrostatic latent image carrier is developed by the liquid developer. When the content of the silicone oil in the liquid developer is 5 wt.%, an image on a transfer body becomes sticky after the fixing is executed.

Abstract: PROBLEM TO BE SOLVED: To obtain a liq. developer forming a visible image which is efficiently transferred to an intermediate transfer body, not causing the deterioration of an image such as blurring and having satisfactory dispersibility of toner particles by specifying the viscosity of a component settled by specified centrifugal settling in a liq. developer. SOLUTION: In this liq. developer, the viscosity of a component settled by centrifugal settling at 3,300r.p.m. for 30min is 1,000 to =1,000cps viscosity of a component settled by centrifugal settling at 3,300r.p.m. for 30min. Higher viscosity is preferable from the viewpoint of image quality but the redispersibility of the solid component is deteriorated in the case of >500,000cp. The pref. viscosity of the solid component is 1,000 to

Abstract: PROBLEM TO BE SOLVED: To obtain liquid developer with which an excellent printed matter is obtained with good reproducibility even in the case of repeating printing by making the supernatant liquid of liquid in which a colorant is dispersed in carrier solvent have specified transmissivity in all the area of a specified wavelength band. SOLUTION: When an electrostatic latent image on an electrostatic latent image carrier is developed and a developed image developed by such development is transferred to a body to be transferred, a toner component happens to be accumulated on the electrostatic latent image carrier by consecutive printing. When the quantity of the toner component is made large, it influences the electric characteristics of the electrostatic latent image carrier and influences the latent image and the image. By using the colorant whose supernatant liquid has the transmissivity of >=60% in all the area of the wavelength of 250 nm to 350 nm when the colorant is dispersed in the carrier solvent, the adhesion of the toner component and the deterioration of the image are hardly caused. It is desirable to use condensed azo pigment and polycyclic pigment as the colorant.
