A double-sided printable image recording apparatus including a conveyer for conveying a recording medium, a fixed recording head for ejecting an aqueous ink and a treating liquid having nature of aggregating a colorant contained in the aqueous ink to a recording medium conveyed by the conveyer, which is arranged in a direction substantially orthogonal to a conveying direction of the recording medium, and has a printing region of a recording medium width, and an ejection controller for controlling ejection of the aqueous ink and the treating liquid from the fixed recording head based on image information, wherein the ejection controller, in a double-sided printing mode of printing on both sides of the recording medium, controls an ejection amount of a treating liquid ejected per recording medium to a smaller amount than that of a single-sided printing mode of printing only on one side, at least on a surface of a recording medium.
