An extractor separates a dispersoid (toner) and a dispersion medium (carrier liquid) from a liquid sample (liquid developer) containing the dispersoid and the dispersion medium and extracts these. The extractor has a first roller that carries a thin layer of the liquid sample containing the dispersoid and the dispersion medium on a circumferential surface thereof and rotates about a shaft. A separating member is in contact with the first roller and separates the dispersion medium from the thin layer carried on the first roller. A charger charges the dispersoid in the thin layer carried on the first roller at a position upstream of a contact position of the separating member with the first roller with respect to a rotating direction of the first roller. An electric field generator generates an electric field for causing the charged dispersoid to be attracted to the circumferential surface of the first roller.

Of carrier liquids extracted by an carrier liquid extracting device from a liquid developer obtained by mixing together yellow, cyan, magenta, and black liquid developers, the carrier liquid of particularly high purity is recycled for concentration control of the yellow liquid developer and the carrier liquid of purity a little lower than the aforementioned purity is recycled for concentration control of the cyan, magenta, and black liquid developers. A carrier liquid extracted from the yellow liquid developer is recycled for the concentration control of the yellow liquid developer, and a carrier liquid extracted from the liquid developer obtained by mixing together the cyan, magenta, and black liquid developers is recycled for the concentration control of the cyan, magenta, and black liquid developers. This permits efficient use of carrier liquids to be recycled without having an influence on the image quality.

When the temperature of the liquid toner has fluctuated by Tor more (Step S: YES), the equation obtained by measuring the liquid toner is modified (Steps Sthrough S). This equation is obtained based on the output voltage value of the concentrated toner liquid sensor, which has the same specifications as those of the liquid toner sensor, and the output voltage value of the carrier liquid sensor, which has the same specifications as those of the liquid toner sensor(Sthrough S). The output voltage value of the liquid toner sensoris entered into the modified equation to calculate the toner solids content of the liquid toner of the storage tank(Step S). Control of the concentration of the liquid toner is carried out based on the calculated toner solids content (Step S).
