  • Publication number: 20080008501
    Abstract: 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.

  • Publication number: 20070223950
    Abstract: When the temperature of the liquid toner has fluctuated by T1 or more (Step S3: YES), the equation obtained by measuring the liquid toner is modified (Steps S4 through S7). This equation is obtained based on the output voltage value of the concentrated toner liquid sensor 27, which has the same specifications as those of the liquid toner sensor 24, and the output voltage value of the carrier liquid sensor 29, which has the same specifications as those of the liquid toner sensor 24 (S4 through S6). The output voltage value of the liquid toner sensor 24 is entered into the modified equation to calculate the toner solids content of the liquid toner of the storage tank 18 (Step S8). Control of the concentration of the liquid toner is carried out based on the calculated toner solids content (Step S9).
