PROBLEM TO BE SOLVED: To provide a droplet discharging device that can be applied regardless of an ink type and that can improve landing accuracy by reducing air resistance with respect to a flying droplet. ! SOLUTION: This droplet discharging device 10 is applied in a printer in which an atmosphere control chamber 20 is placed on a stage 17 and which accommodates a recording medium 18 and an ink jet head (droplet discharging means) 15, the atmosphere control chamber 20 being formed such that the surface of a frame 11 with an ink jet printing part disposed in it is covered with an atmosphere control chamber wall 12 having a gas suction hole 12a1 and a gas discharge hole 12b1. When an ink droplet 19 is discharged onto the recording medium 18, gas g1 with low air pressure atmosphere smaller in density and viscosity than air is supplied from the gas suction hole 12a1, via a gas-suction-side valve va1, as atmosphere for the atmosphere control chamber 20 for air including a space from the ink jet head 15 to the |
