To provide a technique enabling it to form an image in an image forming medium of comparatively wide width, and to improve the resolution capable of forming an image.

The image formation device is composed so that it may include a printer driver section 6a for acquiring the information on resolution of the image for imaging at the time of imaging, a head movement control section 16c for adjusting the angle of a nozzle train 22 against the paper width direction so that the resolution by the nozzle train 22 in the paper width direction perpendicularly intersecting with the carrying direction may become the acquired resolution at the time of imaging, and a printing data transfer processing section 16b for carrying out the imaging in the paper by the nozzle train 22 with its angle adjusted.
