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 (γD1) of the first ink is equal to or more than a static surface tension (γS2) of the second ink.
