タンク。 In a developing tank of a wet electrostatic copying apparatus, the developer tank is adjacent to a rotating body that is rotated on a daily basis, stores a developer, and is equipped with a developer concentration sensor consisting of a light emitter and a photoreceptor facing each other. A wet type characterized in that a cleaning member is provided that moves between the light emitting body and the light receiving body of the sensor in synchronization with the rotation of the rotating body, and the light emitter and the light receiving body are cleaned by the movement of the cleaning member. Developing tank of an electrostatic copying machine.
