Abstract:
Provided are an apparatus and method for measuring the concentration of liquid developer, and an apparatus and method for controlling the concentration of liquid developer in which the concentration of a highly concentrated developer is easily and accurately measured or controlled without controlling the liquid amount. An opening is provided in the developer container for concentration measurement in which a liquid developer for concentration measurement is stored and stirred for concentration measurement. The developer container for concentration measurement is configured such that the stored liquid developer for concentration measurement overflows through the opening at the time of stirring.
