Abstract
An ink supply mechanism, which is provided with an ink supply path to supply ink contained in an ink container to an ink jet recording head for recording images on a recording medium by discharging ink from discharge ports, comprises agitating means provided for the ink supply path for agitating ink flowing in the ink supply path. With the structure thus arranged, ink is supplied to the ink jet recording head in a state of being agitated by agitating means arranged in the ink supply path, thus making it possible to prevent the uneven concentrations of ink in an ink container left intact for a long time from appearing as the uneven densities of recorded images on a recording medium.
