Abstract
Provided is an ink jet recording method which can record an image excellent in abrasion resistance and in which an ink after storage is excellent in filter passability. The ink jet recording method includes ejecting an aqueous ink to a recording medium to record an image with an ink jet recording apparatus including: the aqueous ink; an ink storage bag configured to store the aqueous ink; and a recording head of an ink jet system configured to eject the aqueous ink. The recording head includes, in an inside thereof, a filter configured to pass the aqueous ink therethrough. The aqueous ink contains a pigment, a wax, a dispersant for dispersing the wax and a resin particle.
Claims21
An ink jet recording method comprising ejecting an aqueous ink to a recording medium to record an image with an ink jet recording apparatus comprising:
