Liquid ejecting head and liquid ejecting apparatus

A liquid ejecting head comprising:

• an ejection port for ejecting liquid;
• a pressure chamber including an element for generating energy to eject liquid from the ejection port;
• a first individual flow path for supplying liquid to the pressure chamber;
• a second individual flow path for supplying liquid to the pressure chamber;
• a first common flow path for supplying liquid to the first individual flow path;
• a second common flow path for supplying liquid to the second individual flow path;
• a first opening connecting with the first common flow path;
• and
• a second opening connecting with the second common flow path,
• wherein in the liquid ejecting head, a first circulation for causing liquid to flow in the order of the first opening, the first common flow path, the first individual flow path, the pressure chamber, the second individual flow path, the second common flow path, and the second opening, and a second circulation for causing liquid to flow in the reverse order of the first circulation are switched,
• a flow path resistance of the first common flow path from the first opening to the first individual flow path in the furthest position from the first opening is less than a flow path resistance of the second common flow path from the second opening to the second individual flow path in the furthest position from the second opening, and
• a flow path resistance of the first individual flow path is less than a flow path resistance of the second individual flow path.

A liquid ejecting apparatus comprising:

• a liquid ejecting head;
• and
• a switching unit configured to switch between a first circulation and a second circulation,
• the liquid ejecting head including:
• an ejection port for ejecting liquid;
• a pressure chamber including an element for generating energy to eject liquid from the ejection port;
• a first individual flow path for supplying liquid to the pressure chamber;
• a second individual flow path for supplying liquid to the pressure chamber;
• a first common flow path for supplying liquid to the first individual flow path;
• a second common flow path for supplying liquid to the second individual flow path;
• a first opening connecting with the first common flow path;
• and
• a second opening connecting with the second common flow path,
• wherein in the liquid ejecting head, the first circulation for causing liquid to flow in the order of the first opening, the first common flow path, the first individual flow path, the pressure chamber, the second individual flow path, the second common flow path, and the second opening, and the second circulation for causing liquid to flow in the reverse order of the first circulation are switched,
• a flow path resistance of the first common flow path is less than a flow path resistance of the second common flow path,
• a flow path resistance of the first individual flow path is less than a flow path resistance of the second individual flow path, and
• the liquid ejecting apparatus causes the liquid ejecting head to perform an ejection operation based on ejection data while switching between the first circulation and the second circulation by using the switching unit.
