Abstract:
Provided is an ink jet recording method capable of suppressing deterioration in an ejection property when voltage control of a recording head is performed. The ink jet recording method includes using an ink jet recording apparatus having a recording head equipped with a heater, a first protection layer and a second protection layer made of a metal material, and a unit of applying a voltage with the second protection layer as a cathode and an ink-mediated conduction site as an anode and ejecting the ink from the recording head to record an image on a recording medium, wherein the ink is an aqueous ink containing a component having an anionic group and a soluble metal ion having a standard electrode potential of more than 0 V.

Claim (Index 9):
An ink jet recording apparatus comprising\n a recording head equipped with\n a heater placed in an ink flow path communicated with an ejection orifice, \n a first protection layer placed at a position corresponding to the heater and blocking a contact between the heater and an ink in the ink flow path, and \n a second protection layer placed at a position corresponding to the heater and to be brought into contact with the ink and made of a metal material, \n wherein the ink comprises an aqueous ink containing a component having an anionic group and a soluble metal ion having a standard electrode potential of more than 0 V and having a content (ppm) of the metal ion of 0.1 ppm or more to 15.0 ppm or less based on a total mass of the ink, and the ink jet recording apparatus comprises a unit of applying a voltage with the second protection layer as a cathode and an ink-mediated conduction site as an anode.
