Abstract:
An ink jet recording apparatus comprising:a recording head in which when a plurality of pressure generation elements corresponding to a plurality of nozzle openings, respectively, pressurize ink in a pressure generation chamber connected to said nozzle openings, ink droplets are discharged to a recording medium through said nozzle openings; temperature detection means for detecting a temperature of said recording head; detection timing control means for allowing said temperature detection means to detect the temperature of said recording head at a predetermined timing; drive signal generation means for generating a drive signal for driving said recording head; temperature correction means for adjusting a drive waveform of said drive signal based on the detecting result of the temperature by said temperature detection means, so that the amount of the ink droplets becomes constant without dependence on the temperature; and recording stop monitor means for monitoring whether the discharging of the ink droplets is stopped or not, wherein on the basis of a monitor result of said recording stop monitor means, when the discharging of the ink droplets is stopped, said detection timing control means allows said temperature detection means to detect the temperature of said recording head until the discharging of the ink droplets starts.
