Abstract: A method of forming an image on a recording medium using an ink jet recording apparatus. The ink jet recording apparatus includes a recording head in which a plurality of recording element substrates is arranged to form joint portions and a plurality of wipers is arranged to form wiper overlapping portions. The method includes ejecting a first ink from a first ejection orifice array, ejecting a second ink from a second ejection orifice array, and the plurality of recording element substrates with the plurality of wipers. The first ejection orifice array is wiped and then the second ejection orifice array is wiped. At least a part of the wiper overlapping portion wipes the joint portion. A dynamic surface tension (?D1) of the first ink is equal to or more than a static surface tension (?S2) of the second ink.

Abstract: Inkjet recording is performed by using an inkjet recording apparatus including an ink circulation channel for circulating a first ink, an ink supply channel for supplying a second ink into the ink circulation channel, and a recording head communicating with the ink circulation channel. The apparatus is configured to eject an aqueous ink including the first ink and the second ink from the recording head, thereby recording an image on a recording medium. The content (% by mass) of water in the first ink and the content (% by mass) of water in the second ink differ from each other by 2.00% by mass or more. The first ink contains a pigment, and the second ink contains a first water-soluble organic solvent having a log P value of ?1.10 or more and a surfactant.
