PURPOSE:To eliminate a force cooling and to provide a rapid, positive and accurate response in a liquid pressure control recording method by the heating of a recording liquid in which a thermal acting surface contacting with the liquid to be heated is changed to a specified temperature to cause the time to be a specified value. CONSTITUTION:When the pulse signal which is turned ON or OFF at the times tO and tP is applied to the heater means 2, a surface temperature at the thermal acting surface 9 contacting with the thermal acting part 7 of orifice 5 being heated is changed from a starting temperature Ti to the maximum temperature Tp as the time is passed and shows a variation illustrated in a curve. When the value is 0< tau0<= 10mus, the relation of tau0<=tau1/2<=4tau0 is defined and when the value is 10mus<tau0, the relation 10mus<=tau1/2<=4tau0 is defined, then it is technically possible to have a rapid rise-up curve. In turn, when the energization to the thermal resistance layer 11 is turned off, the heat found at the thermal acting part 7 and the heat generating part 8 is discharged rapidly to the base plate 3 side. |
