Droplet ejecting head and image forming device

A droplet ejecting head that ejects droplets onto a recording medium that is conveyed by a conveying unit that conveys the recording medium while causing the recording medium to closely contact a peripheral surface of a drum, the droplet ejecting head comprising:

• a plurality of ejecting openings that are provided so as to be lined-up in a conveying direction of the recording medium onto which the droplets are ejected, and in an cross-conveying direction that crosses the conveying direction,
• wherein distances, in the conveying direction of the recording medium, of the respective ejecting openings are determined in accordance with timings at which the respective ejecting openings eject the droplets, an ejecting speed of the droplets, a conveying speed of the recording medium, and a radius of the drum, such that positions, along the conveying direction of the recording medium, at which the droplets ejected from the ejecting openings land, substantially coincide at all of the ejecting openings.
