摘要:
A recording head comprises an ink container (IJC), an energy generating device (91) for discharging ink from the ink container, an ink discharge section corresponding to the energy generating device and a covering member that covers the ink discharge section and an atmosphere-communicating opening for the ink container, wherein when the recording head is out of recording, a small opening communicating with the atmosphere-communicating opening, or a valve member (22) capable of opening or closing in accordance with an internal pressure change, or an internal pressure change-absorbing member capable of absorbing an internal pressure change by changing its volume is provided on said covering member at a position corresponding to the atmosphere-communicating opening.
