Abstract

PURPOSE:To reduce fluid resistance and to increase frequency of conversion into particles by a construction wherein a bypassing path is formed between a communication path and an ink supply path. CONSTITUTION:A bypassing path F adapted to pass ink directly from an ink supply chamber to a communication path B not through a pressure chamber C is provided between an ink supply path D and the communication path B. Refilling of ink after jetting is performed such that pressure in the communication path B is lowered due to surface tension at a nozzle A and pressure at a position P1 in the bypassing path F becomes lower than that at a position P2, whereby ink flows in the direction of arrows G1, G2 into the communication path B, while ink from the ink supply path D flows in the direction of arrows H1, H2. Thus, ink also flows through the bypassing path F thereby to assist refilling.
