摘要： A pressure adjustment mechanism can provide ink to a subtank with the inside of the subtank being opened to outside air, by using a low driving force. A liquid tank holds liquid to be used by a printing apparatus. The liquid tank has a structure in which a capacity of the liquid tank can be changed so as to generate a negative pressure in the liquid tank. The liquid tank includes a case having an opening at one side of the tank, and a flexible film that covers the opening, and a compressed spring in the tank for pressing the film outwards.

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.

摘要： An ink cartridge removably mountable in an image forming apparatus includes a flexible storage member, a pressurization-space formation member, an output port, and an opening-and-closing assembly. The flexible storage member stores ink. The pressurization-space formation member hermetically houses the storage member and forms a pressurization space to which a fluid is supplied between the pressurization-space formation member and the storage member. The output port is connected to the storage member, through which the ink is supplied from the storage member to the image forming apparatus. The opening-and-closing assembly opens and closes between the output port and the storage member by the fluid supplied into the pressurization space.
