Claim 7:
8. An ink jet recording method comprising:
recording an image on a recording medium by applying at least one of pigment ink containing pigment and dye ink containing dye from an ink jet recording head onto a surface of the recording medium on a side having a first ink-receiving layer and a second ink-receiving layer,
wherein the recording medium comprises:
a substrate;
the first ink-receiving layer; and
the second ink-receiving layer adjacent to the first ink-receiving layer, in this order,
wherein
the first ink-receiving layer contains first inorganic particles having an average primary particle size of 50 nm or less,
the first inorganic particles are particles of at least one material selected from the group consisting of fumed silica, fumed alumina, and hydrated alumina, and
the first ink-receiving layer has a positive surface zeta potential, and
wherein
the second ink-receiving layer contains second inorganic particles having an average primary particle size of 50 nm or less,
the second inorganic particles are particles of at least one material selected from the group consisting of fumed silica, fumed alumina, and hydrated alumina,
the second ink-receiving layer has a negative surface zeta potential, and
the second ink-receiving layer has a thickness of 2 μm to 15 μm.
