Abstract
A device for measuring the concentration of a developer liquid for a liquid-type printer, including a container having a discharge portion, first and second rotary members rotatably installed in the container with a predetermined space, and a supply portion for supplying the developer liquid containing toner particles and liquid carrier into the space between the first and second rotary members. A concentration detector is provided for detecting the concentration of the developer liquid by emitting light onto the developer liquid flowing along the space between the first and second rotary members, and receiving the light passed through the developer liquid. In the concentration measuring device, the space between the first and second rotary members can be adjusted to be smaller, and the concentration of a developer liquid having a low light transmittance can also be measured.
