PURPOSE:To keep the viscosity of ink constant for stabilizing the discharge of ink droplets by controlling the temperature of ink by the circulation of a liquid medium around an ink tank. CONSTITUTION:For example, in an ink tank 8 having a double structure consisting of an outer wall 14 and an inner wall 15, a liquid medium 17 of a certain temperature is circulated. Thus, the temperature of ink in the tank 8 can be kept constant and therefore, ink having stabilized viscosity can be stably ejected in stable liquid droplets 12 to a recorder 13. EFFECT:The ink supplier is compact. |
