摘要： A concentration detection device includes a tubular member, a light-emitting member, and a light-receiving member. The tubular member includes a liquid developer inlet that inlets liquid developer, and a liquid developer outlet that discharges the liquid developer. A liquid channel through which liquid developer passes is formed in the interior of the tubular member. The light-emitting member is a member that is disposed on one end of the tubular member. The light-receiving member receives light emitted from the light-emitting member that detects concentration of the liquid developer that is inlet into the interior of the tubular member.
摘要翻译：浓度检测装置包括管状部件，发光部件和受光部件。管状构件包括：液体显影剂入口和液体显影剂排出液体显影剂出口。液体显影剂通过的液体通道形成在管状部件的内部。发光构件是设置在管状构件的一端的构件。光接收部件接收从发光部件发射的光，其检测入口到管状部件内部的液体显影剂的浓度。

摘要： In a density detection device, a casing includes an internal space. An inflow path is communicated with the internal space through an inlet facing the internal space. An outflow path is communicated with the internal space through an outlet facing the internal space. A base is provided in the internal space to block the liquid flowing from the inlet. The base has a top side positioned above the inlet. A movable member has a bottom side opposed to the top side of the base. The movable member is configured to move to cause the bottom side to be close to and away from the top side of the base. A density detection section is configured to detect density of a liquid layer formed between the bottom side and the top side while the bottom side is positioned close to the top side at predetermined distance.
摘要翻译：在密度检测装置中，壳体包括内部空间。流入路径通过面向内部空间的入口与内部空间连通。流出路径通过面向内部空间的出口与内部空间连通。底座设置在内部空间中以阻挡从入口流出的液体。底座的上侧位于入口的上方。可移动部件具有与基部的顶侧相对的底侧。可动构件被构造成移动以使底侧靠近和远离底座的顶侧。密度检测部被配置为检测形成在底侧和顶侧之间的液体层的密度，同时底侧以预定距离位于靠近顶侧的位置。
