• and
• a fluid containing unit configured to supply the recording fluid to the distributing member via the inlet portion and the supply channel portion,
• wherein the supply channel portion includes a flow-directing wall configured to direct a flow of the recording fluid upward before the recording fluid enters the common fluid chamber, and
