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.

摘要： An image forming apparatus includes a recording head, a cap, a suction unit, and a recovery device. The recording head has nozzles at a nozzle face to horizontally eject droplets of liquid. The cap caps the nozzle face of the recording head. The suction unit is connected to the cap. The recovery device drives the suction unit with the nozzle face capped with the cap to create a negative pressure in an internal space of the cap and suck the liquid from the recording head. The cap has a contact portion to contact the nozzle face and a suction port to communicate with the suction unit. The suction port is disposed away from the contact portion with a minute gap at a lowermost area of the cap in a vertical direction.
