ABSTRACT:
In order to detect a toner density in a liquid developer accurately while lowering the influence of ions on the liquid developer, the toner density detecting apparatus 11 detects a toner density in a liquid developer obtained by mixing charged toner particles in a carrier solution. The first and second electrodes 12 and 13 are opposed to each other with a liquid developer therebetween and connected to the first DC power source (V.sub.1) thereby to apply the first electrical field to the liquid developer. The toner density detecting apparatus 11 further includes the third and fourth electrodes 14 and 15 opposed to each other in the direction orthogonal approximately to the direction in which the first and second electrodes 12 and 13 are opposed to each other and connected to the second power sources (V.sub.2, V.sub.3, V.sub.4) thereby to apply the second electrical field. The third electrode 14 is divided into plural sub-electrodes 14a and 14b, and the toner density detecting apparatus 11 further includes circuits (A.sub.1, A.sub.2) for detecting the current values of the sub-electrodes 14a and 14b.
