Abstract
The present invention can reduce the amount of ink in an outlet-side space which is sucked together with gas, without making the thickness of an isolating member for separating the inside of the sub-tank into an inlet-side space and the outlet-side space in the horizontal direction extremely thin nor making an inflow channel for allowing the ink in the inlet-side space to flow into the outlet-side space extremely small. The present invention has an isolating member in the form of a plate for separating the inside of a sub-tank coupled to a recording head into an inlet-side space connected to a main-tank and an outlet-side space connected to the recording head, and an inflow channel in the form of a slit for increasing the ink level in the inlet-side space while allowing the ink in the inlet-side space to flow into the outlet-side space from the isolating member.
