摘要： An image recording apparatus that irradiates a recording target with laser light and records an image thereon, that includes: a laser irradiation device that has plural laser emitting elements, and irradiates the recording target with laser light emitted from the plural laser emitting elements; an irradiation condition adjusting unit that causes the laser irradiation device to emit laser light such that a part of an image dot recorded on the recording target moving relatively to the laser irradiation device overlaps an image dot adjacent thereto, and makes a laser irradiation condition for when image dots forming a boundary between a colored portion and a non-colored portion are recorded, different from a laser irradiation condition for when the other image dots are recorded; and an output control unit that controls the irradiation with the laser light, based on the laser irradiation condition adjusted by the irradiation condition adjusting unit.
