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.

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 an output unit, a pair of output rotary bodies, and a controller. A sheet having an image formed thereon is discharged to the output unit. When plural sheets are sequentially discharged to the output unit, the controller controls overlapping output operation to, with a trailing end portion of a preceding sheet of the plural sheets being held by the pair of output rotary bodies, feed a subsequent sheet of the sheets to between the pair of output rotary bodies to overlap a leading end portion of the subsequent sheet with the trailing end portion of the preceding sheet. With the leading end portion of the subsequent sheet overlapped with the trailing end portion of the preceding sheet, the controller controls the pair of output rotary bodies to rotate to discharge the preceding sheet to the output unit.
