Abstract

PURPOSE:To enable a high-speed recording action, by a method wherein a recessed part is formed on an opposed surface of at least one insulating substrate, and in a slit-form space a gap of an ink holding part connecting to an ink discharge part is made larger in dimension than a gap on the side of the ink discharge part. CONSTITUTION:When a drive pulse according to image information is applied to a heating resistor 13 of a thermal energy applying means 4, an ink 3 is subjected to a thermal energy to be heated. Then, viscosity and surface tension are reduced and conductivity is enhanced. On the other hand, with the application of an electrostatic control pulse to an electrostatic inducing electrode 19, an electrostatic field is formed between the electrode 19 and the surface of the ink 3, whereby the heated ink 3 jets towards a recording sheet 5 to form an ink dot. At this time, a recessed part 9 is formed on an upper insulating substrate 7, and a gap of an ink holding part 12 connecting to an ink discharge part 11 is made larger in dimension than an gap on the side of the ink discharge part 11. In this manner, the resistance in a flow path can be reduced. Thus, the ink 3 is stably supplied, and recording action can be speeded up.
