Abstract: First, second, and third ink absorbing bodies are accommodated in a container of a recovery reservoir in this order from the side corresponding to a bottom surface of the container, so that an introduction chamber is defined in the middle of a recovery space. A lid having a shutter plate and a communication hole is located over the third ink absorbing body. The upper side of the introduction chamber is covered by the shutter plate to suppress volatilization of solvent element of waste ink introduced into the introduction chamber. In addition, the communication hole is located in a portion of the upper surface of the third ink absorbing body, so that solvent element of ink absorbed by the third ink absorption body volatilizes.
