ABSTRACT:
An ink-jet recording head device capable of ejecting ink from an orifice opened on a slit, the ink being fed from an ink feeding port provided at a lower location than the orifice by means of pressure generated in response to an electrical signal, includes an ink conducting path for communicating the ink feeding port with the slit. The ink conducting path includes a first conducting path formed to conduct the ink from the ink feeding port to an upper part of the slit and then to return toward the lower part of the slit to be led to the orifice.
