PROBLEM TO BE SOLVED: To provide a recording head device capable of effectively preventing degrading in printing quality due to harmful increase of a viscosity of ink or clogging in an ejection nozzle by adequately keeping an ejection face of a recording head to be wet in a simple structure. SOLUTION: A humidifying region 130 for vaporizing a humidifying liquid bleeding from a humidifying liquid supply hole 121 is formed on a predetermined region of the ejection face 100 of the recording head device 10. The ejection face 100 can be humidified by the vaporization of the humidifying liquid. COPYRIGHT: (C)2006,JPO&NCIPI |
