ABSTRACT:
The present invention aims to provide an ink tank which can elongate the lifetime of ink jet recording apparatus and further stores therein an ink which can achieve superior image characteristics such as image fastness. The present invention provides an ink tank which includes an ink storage portion storing an aqueous ink therein, having fine channels which retain the aqueous ink by capillary force, wherein the aqueous ink includes at least water and a water-soluble coloring material, and further includes a compound satisfying specific requirements.
