1. A recording device comprising:
a first nozzle group including a plurality of nozzles configured to discharge, to a medium, first dots that are dots of a reaction liquid;
a second nozzle group including a plurality of nozzles configured to discharge, to the medium to which the reaction liquid is discharged, second dots that are dots of ink containing a color material that coagulates with the reaction liquid; and
a control unit configured to control discharging of the first dots by the first nozzle group and discharging of the second dots by the second nozzle group, wherein
the control unit controls arrangement, on the medium, of the first dots discharged by the first nozzle group so as to be more regular than arrangement, on the medium, of the second dots discharged by the second nozzle group, and
the control unit further controls the arrangement of the first dots on the medium such that all distances between adjacent first dots among the first dots in one direction are equal, and the one direction is one of a first direction of the medium and a second direction of the medium which is perpendicular to the first direction.
