Patent ID: 7802865

Claim:
An ink jet printing apparatus configured to print an image by using a printing head capable of ejecting ink by utilizing thermal energy generated upon application of a drive pulse to an electrothermal converter, the printing being performed by applying the ink ejected from the printing head onto a printing medium, the ink jet printing apparatus comprising: an acquiring unit that acquires information on a temperature of the printing head; and a drive controlling unit that controls at least one of a voltage and pulse width of the drive pulse on the basis of the information, wherein the drive controlling unit executes, when the temperature of the printing head is lower than or equal to a predetermined temperature, first control in which the pulse width of the drive pulse is controlled on the basis of the information and the voltage of the drive pulse is kept constant, and wherein the drive controlling unit executes, when the temperature of the printing head is higher than the predetermined temperature, second control in which the voltage and pulse width of the drive pulse are controlled on the basis of the information.
