PROBLEM TO BE SOLVED: To uniformly heat ink so that the weight of the circulating ink may not be fluctuated without using a high temperature heater. SOLUTION: A liquid heating means 26 is constituted of a heater member 31 fixed on a supply means side and a channel pipe 32 wound round the heater member 31. The channel pipe 32 coming into contact with the heater member 31 in a limited space is made longer to secure sufficient channel length for the ink, the ink is heated to a desired state in the small space, and then the ink is sufficiently heated without controlling the heater member 31 to be at high temperature.
