A recording head comprises an ink container, an energy generating device 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 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.

L'invention est une tête d'enregistrement comportant un réservoir d'encre, un générateur d'énergie utilisée pour éjecter l'encre du réservoir, une section de décharge d'encre correspondant au générateur d'énergie et un élément de couverture qui recouvre la section de décharge d'encre et une ouverture communiquant avec l'atmosphère pour le réservoir. Quand la tête d'enregistrement n'est pas en opération, une petite ouverture communiquant avec l'ouverture de communication avec l'atmosphère, ou une soupape pouvant s'ouvrir ou se fermer selon les variations de la pression interne, ou un élément interne absorbant les variations de pression en changeant de volume est incorporé audit élément de couverture à un endroit correspondant à l'ouverture de communication avec l'atmosphère.
