PURPOSE:To solve problems such as increased substrate temperature and resultant generation of temperature gradient and perform high-quality recording free from image blur or color change by using a heating means provided at both ends and in the center of a substrate to control through heating the temperature of the ends and center of the substrate on the basis of temperature data obtained through detection by a temperature sensor. CONSTITUTION:A plurality of liquid channels (nozzles) 4 are provided on a substrate 2, with a liquid discharge port for discharging and injecting flying droplets constituting part of the entire system. Heating means 7, 8a and 8b are provided at three points, i.e. both ends and center of the substrate, in close contact with the substrate bottom in such a way that a plurality of regions of the substrate may be heated independently of each other and/or simultaneously. The heaters 8a, 8b are turned on simultaneously and the heater 7 is connected to a temperature controller so that it may be turned on and heated independently of these heaters 8a, 8b. Thus the substrate temperature can be controlled at a constant level on the basis of temperature data obtained through independent detection by temperature sensor means 9, 10 connected to the temperature controller. |
