Abstract
【解決手段】記録用のノズル列におけるノズル4の並び方向の実質的に延長線上であって、インク供給源から供給されたインクを各ノズル4に分配するためにノズル列に沿って長く形成された共通インク室7におけるインクの流れ方向の最下流側に対応する部位には、気泡排出用の排気口5が少なくとも2個設けられ、少なくとも2個の排気口5は、同一の排気用流通路73を介して共通インク室7における最下流側の部位に接続され、排気口5の1個当たりの開口面積は、前記各ノズル4の開口面積と実質上同等またはそれ以下に形成され、2個以上の排気口を含む排気用流通路の流路抵抗は、ノズルを含むインク流通路の流路抵抗よりも低くされている。
