A recording apparatus includes a storage unit, a supply flow path, a degassing unit, and a temperature adjustment unit. The storage unit stores liquid that is supplied to a recording head that discharges the liquid. The supply flow path connects the storage unit and the recording head. The degassing unit degases the liquid flowing in the supply flow path. The temperature adjustment unit is positioned between the storage unit and the degassing unit and adjusts a temperature of the liquid flowing in the supply flow path.

A liquid ejecting head configured to eject a liquid in a first direction includes: head units arranged side by side in a second direction orthogonal to the first direction and a flow channel member having a first supply flow channel through which the liquid is supplied to the head units, a first collection flow channel through which the liquid is collected from the head units, a first inlet portion through which the liquid is let into the first supply flow channel from the outside, and a first outlet portion through which the liquid is let out to the outside from the first collection flow channel. The first inlet portion and the first outlet portion are disposed near the center of the flow channel member in the second direction.

A liquid discharge head includes an element substrate including an energy generation element configured to generate energy for discharging liquid from a discharge port, and a supporting member which supports the element substrate and in which a liquid chamber configured to supply liquid to the discharge port is formed, wherein a recessed portion communicating with the liquid chamber is formed at a position above the liquid chamber in a vertical direction in an orientation of the liquid discharge head when used, and wherein at least one of surfaces forming the recessed portion is formed of a flexible member configured to absorb vibration of liquid in the liquid chamber.

An image-recording apparatus includes: a first tank defining a first storage chamber; a second tank defining a second storage chamber; a conveying mechanism for conveying sheets along a conveying path extending in a depthwise direction and a widthwise direction perpendicular to a vertical direction and the depthwise direction; and a recording head including a nozzle. Liquid in the first storage chamber is supplied through a communication port to the second storage chamber and then to the recording head through a liquid outlet port. The second storage chamber is positioned further in a first depthwise direction relative to the nozzle and further in a first widthwise direction relative to the conveying path. A volume of a prescribed space above a liquid level equal to a height of the communication port in the second storage chamber is greater than that of a liquid channel between the liquid outlet port and the nozzle.

A flow path unit including a flow path through which a liquid supplied to an ejection unit that ejects the liquid flows includes a removal unit configured to remove a gas. The removal unit includes an inner wall that is provided with an opening in communication with the flow path and that is configured to come into contact with the liquid, and a storage tank including the inner wall and configured to store the liquid. The removal unit removes the gas contained in the liquid flowing through the flow path in the storage tank. The removal unit includes, at a position coming into contact with the liquid in the storage tank, a lyophobic member having a lower lyophilic property with respect to the liquid than that of the inner wall.
