Ink jet recording method and ink jet recording apparatus

An ink jet recording apparatus used for recording an image on a recording medium with an aqueous ink and an aqueous reaction liquid containing a reactant that reacts with the aqueous ink, comprising:

• a reaction liquid application unit configured to apply the aqueous reaction liquid to the recording medium;
• and
• an ink application unit configured to apply the aqueous ink in such a manner that the aqueous ink overlaps with at least part of a region of the recording medium to which the aqueous reaction liquid is applied,
• wherein the aqueous ink comprises a pigment dispersed by action of a carboxylic acid group, a resin particle and a water-soluble organic solvent,
• a rate of increase in particle size of the pigment dispersed by the action of the carboxylic acid group when the pigment comes into contact with the aqueous reaction liquid is 8.0 times or more,
• the resin particle comprises a first resin particle having a rate of increase in particle size of 3.0 times or less when the first resin particle comes into contact with the aqueous reaction liquid,
• a mass ratio of an amount (% by mass) of the first resin particle contained to a total of an amount (% by mass) of a second resin particle having a rate of increase in particle size of more than 3.0 times when the second resin particle comes into contact with the aqueous reaction liquid and an amount (% by mass) of the pigment dispersed by the action of the carboxylic acid group contained in the aqueous ink is 1.2 times or more to 25.0 times or less,
• the water-soluble organic solvent comprises a first water-soluble organic solvent having a vapor pressure of 1.0×10−2 kPa or more,
• a proportion (% by mass) of the first water-soluble organic solvent in the water-soluble organic solvent of the aqueous ink is 50.0% by mass or more, and
• an amount of water absorbed by the recording medium from a start of contact to 30 msec1/2 in a Bristow method is 10 mL/m2 or less.
