Abstract: A transfer recording method includes a first layer forming step of discharging an image forming ink from an ink jet head onto a transfer medium having a release layer to form a first layer, a second layer forming step of discharging an adhesive ink from the ink jet head to form a second layer so as to be superimposed on the first layer, and a thermal transfer step of thermally transferring the first layer and the second layer onto fabric by heating a surface of the transfer medium on which the first layer and the second layer are formed in a state where the surface faces the fabric, in which the image forming ink includes a color material and water, the adhesive ink includes a thermoplastic resin and water, the softening point of the thermoplastic resin is equal to or lower than the temperature for heating the fabric in the thermal transfer step, the solid content of the thermoplastic resin is 5% by mass or more and 25% by mass or less based on the total amount of the adhesive ink, the application amount of the adhesive ink in the second layer forming step is 38 g/m2 or more, and the sum of the application amount of the image forming ink in the first layer forming step and the application amount of the adhesive ink in the second layer forming step is 212 g/m2 or less.
