Abstract

An ink-jet printing apparatus restricts fluctuation of the printing density due to coagulation and settle out coloring agent employing a water based ink, in which a water insoluble coloring agent or the coloring agent having low water solubility is dispersed. By this, movement of the ink caused due to difference of specific gravity caused by coagulation of the coloring agent or so forth in an upper passage, to a lower passage can be restricted to successfully prevent increasing of difference of ink density.
