Abstract
A liquid jet recording head includes a liquid path member having a plurality of liquid flow paths, each of the liquid flow paths being filled with a recording liquid, an orifice being formed at an end of each of the liquid flow paths, and a heater base member having a plurality of heater members and a plurality of radiator members. The heater base member is connected to the liquid path member, each of the heater members having a heater portion, the heater portion generating heat in accordance with a power supplied to it. Each of the radiator members is thermally coupled to the heater portion of one of the heater members so that the amount of heat transmitted from the heater portion to the recording liquid on the heater portion changes in a predetermined direction. When a power is supplied to the heater portion, a bubble is generated in the recording liquid and located at an area on the heater portion, the area having a size corresponding to the power supplied to the heater portion, the bubble causing a recording liquid droplet to be jetted from the orifice.
