Description

ABSTRACT:
An ink-jet recording apparatus is provided which can be composed of fewer number of parts and easily controlled. In the ink-jet recording apparatus, one pressurized unit such as a pressurized pump for ink supply is used. An open/close state switching member which opens/closes an air communication hole of a sub-tank is integrally formed with an ink supply member which supplies ink within a main tank to the sub-tank. Accordingly, depending on a relative position between the ink supply member and the sub-tank, the operation mode is easily switched to at least following three modes: recording mode, ink supply mode (standby mode), and discharge performance recovery mode.
