Abstract:
1. A toner concentration adjusting system, comprising: a toner concentration adjusting tank configured to store a first wet type developer containing toner and dispersion medium; a concentration detecting section configured to measure a first control value corresponding to viscosity which is a substitute characteristic of toner concentration of the first wet type developer in the toner concentration adjusting tank; a concentrated developer supply section configured to supply the toner concentration adjusting tank with a concentrated developer having a toner concentration higher than a predetermined standard toner concentration; a dispersion medium supply section configured to supply the toner concentration adjusting tank with dispersion medium; a supply control section configured to control the concentrated developer supply section and the dispersion medium supply section so that the first control value measured by the concentration detecting section gets close to a first control target value corresponding to viscosity which is a substitute characteristic of toner concentration of the wet type developer with the standard toner concentration, the supply control section including:
