Abstract
In an ink jet recording apparatus, a recording head is mounted on a carriage which reciprocately moves in a widthwise direction of recording paper. A subtank is mounted on the carriage for supplying ink. A main tank stores ink which is replenished to the subtank. An ink amount detector detects an amount of ink stored in the subtank. A replenishment controller controls replenishment of ink stored in the main tank to the subtank, in accordance with the ink amount detected by the ink amount detector.
