Abstract
An ink-jet recording head for discharging ink by imparting heat energy to the ink, wherein heaters (8a, 8b) for warming a board are provided on the board (1) provided with a discharging heater array (6) as a group of discharging warming heaters (5) for generating thermal energy at both sides of the discharging heater array (6) as well as sensors (2a, 2b) for detecting the temperature of the board are provided. Each of the sensors is disposed at the positions, at which a time required for the influence due to temperature change only when a predetermined ink discharging heater is energized, reaches said positions is substantially equal to a time required for the influence due to temperature variations when each of the warming heaters (8a, 8b) is energized, reaches said positions. Therefore, the recording head temperature control can be carried out with a high degree of accuracy and at excellent response in a stabilized mode.
