Disclosed is a recording method in which an image is first formed on an intermediate transfer medium by ejection of ink and is then transferred to a printing medium. The present invention solves a problem regarding insufficient transfer of the image to the printing medium, which is caused by roughness on a surface of the ink image formed on the intermediate transfer medium due to non-uniform application amounts of ink. A transferability improving agent is applied in a controlled manner to an ink image which has been formed on a transfer drum by application of ink. The transferability improving agent is applied in a larger amount to regions with a relatively small application amount of the ink as compared with regions with a relatively large application amount of the ink.
