Abstract: Provided are an image recording apparatus, a dither mask, and an image recording method capable of reducing occurrence of concentration unevenness without decrease in productivity. In an image recording apparatus that repeats a main scan operation of relatively moving a recording head having a nozzle row with respect to a recording medium in a main scan direction to perform recording and a sub scan operation of relatively moving the recording medium with respect to the recording head in a sub scan direction, a nozzle jetting rate of each nozzle is controlled by a dither mask. The dither mask is subjected to threshold setting so that a sum of a sum of nozzle jetting rates of corresponding nozzles of respective nozzle groups used in recording a first half scan for recording each scan band and a sum of nozzle jetting rates of corresponding nozzles of respective nozzle groups used in recording a second half scan becomes a specific value that is in a defined allowable range, with respect to at least a part of a recording duty range.
