摘要： A drying device includes a drier, a gas circulator, and a concentration adjuster. The drier warms a liquid composition on a drying target object. The gas circulator circulates a gas containing a volatile component of an organic solvent warmed and volatilized by the drier to reuse the gas for drying. The concentration adjuster adjusts a concentration of the volatile component reused.

摘要： An inkjet recording method includes applying one or more drive pulses to a pressure generating device of a recording head including a nozzle plate, a liquid chamber, and discharging droplets of ink from the nozzle. Also, the following conditions 1 and 2 are satisfied.1. The ink has a dynamic surface tension 10 mN/m or more greater than the static surface tension of the ink when the surface life length is 15 ms and 3 mN/m or more greater than the static surface tension of the ink when the surface life length is 1,500 ms, as measured by maximum bubble pressure technique at 25 degrees C.2. At least one of the drive pulses has a voltage changing portion to draw in the ink, the voltage changing portion having a changing time of one third or more of the resonance period of the liquid chamber.
