PURPOSE:To improve resolving power, to obtain high quality printing and to perform continuous printing or high speed printing, by separating a glass glaze layer for heat insulation between heat generating resistors. CONSTITUTION:A glass glaze layer 2 is provided to a heat insulating substrate 1 and a large number of heat generating resistors 3 are further respectively independently provided thereon in parallel so as to provide a predetermined interval therebetween, and individual electrodes 4 and a common electrode 5 are connected thereto. The glass glaze layer 2 being a heat insulating layer is separated by forming separation parts 7 thereto at every heat generating resistors. Therefore, when a current is selectively supplied to each of the individual electrodes 4 to generate heat from the selected resistor 3, there is not heat conduction between the adjacent heat generating resistors due to the glass glaze layer 2 and heat is separated at every heat generating resistor. Therefore, resolving power is enhanced and high quality printing generating no tailing, blur or the like can be obtained and high speed printing or continuous printing becomes possible. |
