Abstract

An image forming apparatus includes a recording head (10), a liquid tank (76), a head tank (30), a liquid supply passage (41), a liquid supply passage (41), a liquid intake port (202), a valve member (240), and a lock unit (220, 245, 250). The lock unit (220, 245, 250) is disposed in the head tank (30) to lock and unlock the valve member (240) in response to a change in pressure within the head tank (30). In a locked state, the valve member (240) closes the liquid intake port (202) in immovable state to constantly stop flow of the liquid into the head tank (30). In an unlocked state, the valve member (240) is movable to open and close the liquid intake port (202) in response to a change in pressure within the head tank (30) to regulate the flow of the liquid into the head tank (30).
