Patent attributes
An ink-jet recording apparatus includes a judging unit that judges an ink residual amount of an ink container, a pair of electrodes that are in contact with ink in the ink container and that are spaced apart, a detecting unit that detects an electrical characteristic between the pair of electrodes, a first route that is formed so as to connect the pair of electrodes via the ink in a state that the ink in the ink container is more than a prescribed amount, and a second route that connects the pair of electrodes in a state that the ink in the ink container is of the prescribed amount or less, the second route establishing electrical continuity though it is different from the first route in the electrical characteristic between the pair of electrodes via the ink.
