The ink composition comprises at least a pigment, a compound represented by formula (I), water, and a water-soluble organic solventwherein R1to R7each independently represent an alkyl group; j and k are an integer of 1 or more; EO represents an ethyleneoxy group; PO represents a propyleneoxy group; and m+n is an integer of 1 or more.
