摘要： A droplet discharge device having a droplet discharge head provided with a plurality of nozzles that discharge droplets; a plurality of pressure chambers communicating with the nozzles; and a plurality of pressure generating units for changing a capacity of each pressure chamber by applying a drive signal. The drive signal includes an expansion pulse and a contraction pulse, and the plurality of nozzles are divided into a plurality of groups each comprising one or more nozzles. A drive voltage value of the expansion pulse is set to be common to the respective groups. The drive signal which has a drive voltage value of the contraction pulse independently set in accordance with a droplet speed level for each group is applied to the droplet discharge head, and the droplets are discharged.

摘要： An ink jet recording apparatus includes: a head that ejects droplets of ink; a flow passage portion; and a temperature adjustment unit. The flow passage portion supplies the ink to the head. The flow passage portion includes, in a part thereof, a reservoir unit that reserves the ink. The temperature adjustment unit is capable of adjusting temperatures of the flow passage portion and the head independently of each other. The temperature adjustment unit controls the temperatures of the flow passage portion and the head so that the ink in the head becomes liquid from solid after ink in the flow passage portion is turned to liquid from solid.
