Abstract
In a container, an ink exhausting detecting liquid permeable sponge and an ink permeable sponge are disposed with an isolation film therebetween. The ink exhaustion detecting liquid is oil based, and has a resistance value higher than that of ink, and a specific gravity smaller than that of ink. In usage, the isolation film is drawn out of the container, whereby the ink exhaustion detecting liquid permeable sponge is brought into contact with the ink permeable sponge.
