Abstract
An ink cartridge for reserving an ink in an inner space defined therein, including: (a) an ink supplying portion provided to face a lower portion of the inner space so as to allow supply of the ink from the inner space therethrough; (b) an air introducing portion provided to face the lower portion of the inner space so as to allow introduction of an air into the inner space therethrough; (c) at least one electrode receiver for receiving first and second electrodes, such that the first and second electrodes face the inner space; and (d) a bubble-path-formation restrainer restraining an electrical path allowing a continuity between the first and second electrodes, from being formed of a bubble which is generated as a result of the introduction of the air into the inner space. Also disclosed is an inkjet recording apparatus including the above-described ink cartridge and a detector which detects an electrical characteristic between the first and second electrodes.
