Abstract:
1. An ink jet printing apparatus that uses a printing head and ejects ink from the printing head to a surface of a printing sheet, which has air permeability from an obverse side of the printing sheet to a reverse side of said printing sheet, said apparatus comprising: transporting means for transporting the printing sheet relatively to the printing head; reacting liquid applying means provided on a location along a transporting path of said transporting means so as to apply a reacting liquid, which reacts with ink ejected to a face of the transported printing sheet from the printing head, to a whole area of said printing sheet; and suction means provided on a location along the transporting path of said transporting means so as to apply a suction force on the transported printing sheet in a direction from the obverse side to the reverse side of said printing sheet in order to move the reacting liquid to an inside of the printing sheet, wherein the suction force applied by said suction means is determined so that a reacted product of the ink and the reacting liquid is uniformly distributed in an inside of a layer of the printing sheet.
