An Ink Retaining Container Having an absorption Member Using an Adsorbent for Ink Jet Use an Ink Supply System Having Such Adsorption Member and an Ink Jet Recording Apparatus

摘要

The present invention is greater than the adsorption capacity for a coloring agent contained in the adsorption capacity for the hydrophobic substance contained in ink ink, the present invention relates to an adsorbent for ink jet that is arranged at a position where contact with the ink. Ink holding vessel comprises a ventilation hole for communicating the ink retaining portion for retaining ink to be supplied to the ink jet head, the ink supply opening through which the ink supply portion of the head from the ink containing portion and the ink containing portion and the outside air. The ink containing container comprises a suction member arranged on the part in contact with ink in the container. With the adsorbent and the ink retaining container thus arranged, by removing the hydrophobic substance eluted from the ink absorbent in the ink retaining container it can be effectively carried out the printing characteristics superior ink-jet recording.
