摘要： An ink jet recording method in which an image is formed by applying onto a recording medium a reaction liquid, an aqueous pigment ink containing an anionic polymer aggregatable by the reaction liquid and a resin-containing aqueous liquid containing an anionic polymer aggregatable by the reaction liquid to form an image, the method including the steps of applying the reaction liquid to the recording medium; applying the aqueous pigment ink to a surface of the recording medium to which the reaction liquid is applied by an ink jet method to form an image; and applying the resin-containing aqueous liquid to the image formed on the recording medium by the ink jet method. The surface tension of the resin-containing aqueous liquid is higher than the surface tension of the aqueous pigment ink.

摘要： An ink jet recording method for recording an image on a recording medium using a recording head includes executing relative movement between the recording medium and the recording head in a second direction intersecting a first direction in which a plurality of recording elements are arrayed. The recording head is controlled so that the plurality of recording elements in each group of respective driving blocks of recording elements are driven in order and at a predetermined time interval between respective driving blocks. A plurality of element arrays are driven so that pixels, based on recording data for one column extending in the first direction, are recorded by using the plurality of element arrays within an area of the recording medium corresponding to relative movement width of the relative movement in the second direction within the predetermined time interval.
