<p>A liquid delivering device and a liquid delivering method, which make it possible to easily increase the processing accuracy for the ink delivery section, to reduce such variations as in the ink drop delivery quantity and delivery angle even if dust mixes into the ink, and to prevent the lowering of the rate of feeding ink to the ink delivery section. An ink delivering device comprises a plurality of heating resistors (13) disposed on a substrate member (11), an ink liquid chamber for pressurizing the ink by the energy produced by the heating resistor (13), and a nozzle having a delivery port for delivering the ink pressurized in the ink liquid chamber, wherein the nozzle (17) is disposed on each heating resistor (13), and the opening surface of the nozzle (17) on the heating resistor (13) side is used as an ink inflow port (17b) and the other opening surface as an ink delivery port (17a), whereby the inner space of the nozzle (17) also serves as an ink liquid chamber without separately independently forming such ink liquid chamber.</p> |
