Abstract:
1. An image forming device comprising: a droplet ejecting head that ejects droplets with respect to a recording medium, and that can form a plurality of dots of different diameters; and a control unit that, on the basis of image data expressing a tone value of each pixel in an image that is to be formed on the recording medium, controls sizes of droplets ejected from the droplet ejecting head such that, in a case in which the tone value is within a predetermined tone range, first dots, whose diameter is greater than a predetermined diameter, are formed at a recording rate that satisfies following formula (1), and second dots, whose diameter is less than or equal to the predetermined diameter, are formed at a recording rate corresponding to the tone value: wherein i is a number from 1 to N that is given to respective dots in order from a smallest diameter with a number of the plurality of types of dot diameters being N, α
