Ink jet recording apparatus and ink jet recording method

An ink jet recording apparatus comprising:

• an image forming unit configured to form an ink image containing an aqueous liquid component and a coloring material on an ink receiving medium;
• a liquid absorbing member including a porous body that comes into contact with the ink image, the porous body being configured to absorb at least a part of the aqueous liquid component from the ink image to concentrate an ink constituting the ink image;
• and
• a plurality of pressure applying units configured to press the ink image on the ink receiving medium by the porous body of the liquid absorbing member,
• wherein the plurality of pressure applying units include a first pressure applying unit configured to press the ink image to absorb at least a part of the aqueous liquid from the ink image and a second pressure applying unit configured to press the ink image, from which the at least a part of the aqueous liquid has been absorbed, and
• an average pore diameter of a portion of the porous body pressed by the second pressure applying unit is greater than an average pore diameter of a portion of the porous body pressed by the first pressure applying unit.

An ink jet recording apparatus comprising:

• an image forming unit configured to form a first image containing a first liquid and a coloring material on an ink receiving medium;
• a liquid absorbing member including a porous body that comes into contact with the first image, the porous body being configured to absorb at least a part of the first liquid from the first image;
• and
• a plurality of pressure applying units configured to press the first image on the ink receiving medium by the porous body of the liquid absorbing member,
• wherein the plurality of pressure applying units include a first pressure applying unit including a first roller to press the first image to absorb at least a part of the first liquid from the first image and a second pressure applying unit including a second roller to press the first image, from which the at least a part of the first liquid has been absorbed, and a roller radius of the first roller is greater than a roller radius of the second roller.
