Abstract
A liquid supply device and an image recording apparatus that do not cause the tearing of a diaphragm even if abnormal pressure is generated. The objective is solved by a liquid supply device that includes a back-pressure tank and a restriction member. The back-pressure tank is provided between an ink jet head and a pump, and includes a liquid chamber that communicates with an ink passage through a flow port, a gas chamber in which gas is stored, and an elastic diaphragm that isolates the liquid chamber from the gas chamber. The restriction member is disposed on an extension surface of the flow port of an inner wall surface of the liquid chamber, and keeps the elastic diaphragm on the inside of the extension surface in a case in which the elastic diaphragm is sucked into the flow port by pressure that is applied to ink by the pump.
