Patent ID: 8794729

Claim:
An image recording apparatus configured to record an image by discharging ink onto a recording medium based on recording data, the image recording apparatus comprising: a discharge head including a discharge port array in which a plurality of discharge ports configured to discharge the ink is arranged in an arrangement direction; a heating unit configured to heat the recording medium; a scanning unit configured to cause the discharge head to relatively scan a unit region on the recording medium a plurality of times in a scanning direction intersecting with the arrangement direction in such a manner that respective different divided portions, among a plurality of divided portions formed by dividing the discharge port array, face the unit region by the respective plurality of times of scanning; and a generation unit configured to generate recording data to be used in the respective times of scanning of the discharge head on the unit region by employing a divided pattern, which corresponds to each of the different portions of the discharge port array and includes an arrangement of recording permitting pixels that determine permission of recording onto the unit region and recording non-permitting pixels that determine nonpermission of recording onto the unit region, for image data corresponding to the unit region, wherein an average of distances between each of the recording permitting pixels and the recording permitting pixel located at a close position thereto in the divided pattern corresponding to a region that has a first temperature when the discharged ink is applied onto the recording medium is longer than an average of distances between each of the recording permitting pixels and the recording permitting pixel located at a close position thereto in the divided pattern corresponding to a region that has a second temperature higher than the first temperature when the discharged ink is applied onto the recording medium.
