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).

Provided are a light-emitting portion having a light-emitting member and a light emergence surface through which light from the light-emitting member emerges, and a light-receiving portion having a light incidence surface through which the light from the light-emitting member enters and a light-receiving member that detects the light entering through the light incidence surface. The light-emitting portion and the light-receiving portion can make relative movement between a measurement position in which the light emergence surface and the light incidence surface make contact with each other and a waiting position in which the light emergence surface is away from the light incidence surface. When the light-emitting portion and the light-receiving portion are in the measurement position, the light emergence surface and the light incidence surface make contact with each other at a point.

In the intermediate transfer belt of the present invention, a toner image formed on a plurality of photoreceptors is transferred and temporarily retained. The intermediate transfer belt comprises a reinforcing layer to reinforce the intermediate transfer belt and a surface protection layer that is stacked on the reinforcing layer through a middle layer and contacts the photoreceptors. The reinforcing layer and the surface protection layer have a larger value of surface resistance than a value of volume resistance of the whole belt. This makes it possible to prevent electric charge (voltage) from flowing out to rollers and image forming units and put proper electric charge (voltage) on the intermediate transfer belt. Preferably, the values of surface resistance of the reinforcing layer and the surface protection layer are 1&#xd7;10to 1&#xd7;10&#x3a9;/&#x25a1; and the value of volume resistance of the whole intermediate transfer belt is less than 1&#xd7;10&#x3a9;&#xb7;cm.
