摘要： An image forming apparatus includes a first path through which liquid is supplied to a recording head; a second path connected to a liquid tank; a pressure-adjustment valve connecting the first path with the second path, wherein resistance inside the pressure-adjustment valve changes according to a flow rate of the liquid flowing through the first path; a third path connecting the second path with the pressure-adjustment valve, wherein the third path includes a pump; a fourth path that connects the recording head with the liquid tank and bypasses the pressure-adjustment valve; and an opening/closing valve that opens/closes the fourth path. When an environmental temperature exceeds a threshold, liquid is supplied to the recording head by operating the pump and opening the fourth path. When the environmental temperature is less than the threshold, liquid is supplied to the recording head by operating the pump and closing the fourth path.

摘要： An image forming apparatus includes a recording head, a liquid tank, a first fluid flow path supplying liquid to the recording head, a second fluid flow path being in communication with the liquid tank, a pressure adjusting valve allowing fluid communication between the first and the second fluid flow paths, a cap member covering a nozzle surface of the recording head, and a suction unit being in communication with the cap member. The pressure adjusting valve includes a movable member movably disposed in the internal fluid flow path, wherein the movable member includes a sealing unit that seals the communication between the first and the second fluid flow paths when the cap member covers the nozzle surface of the recording head and a negative pressure is generated in a cap-member space formed between the cap member and the nozzle surface by driving the suction unit.

摘要： An image forming apparatus includes a liquid ejection head, a head tank, a liquid storage container, a liquid feed device, a supply valve, an exhaust passage, a float valve, an air release valve, and a suction device. The exhaust passage is disposed in the head tank and communicated with an ambient air. The float valve is disposed in the head tank to close the exhaust passage in response to an amount of liquid in the head tank. The air release valve opens and closes the exhaust passage of the head tank. When the suction device exhausts air from the exhaust passage with the air release valve open, the liquid feed device is driven to pressurize and feed the liquid.
