Abstract (en)
[origin: EP2639071A1] According to an aspect of the invention, in a liquid ejection recording apparatus (10) which includes an inkjet head (24; 24C, 24M, 24Y, 24K) provided with a liquid ejection surface (70D) having lyophilic properties with respect to a dryable liquid having a component that is volatile in air, the inkjet head being used in a state where the liquid ejection surface is covered with liquid, a non-ejection drive voltage (200, 210) which does not cause ejection of liquid from a nozzle is supplied to the pressurization device (80), so as to cause liquid inside the nozzle to vibrate and to overflow out onto the liquid ejection surface, as well as causing a flowing movement of liquid which covers the liquid ejection surface, whereby increase in the viscosity of the liquid due to drying is suppressed.
