摘要： An ink jet printing apparatus prevents deterioration of the printed image resulting from degradation of refilling characteristics caused by a rise of the printing head temperature as well as decrease in the printing speed. More particularly, the temperature of the ink ejecting head is measured so that the settings of a pulse width and a drive voltage of a drive pulse to be applied to an electro-thermal converting element are altered based on the measured temperature of the ink ejecting head in such a manner that the pulse width is shortened and the drive voltage is increased as the temperature of the ink ejecting head rises.

摘要： Energy applied to a heater for ejecting an ink is set to more than bubble generation threshold energy Eth and less than predetermined energy Eo, or to more than the predetermined energy Eo. Thereby, when an image to be printed is one of low ejection duty, an ejection where a bubble communicates with the atmosphere before the ink droplet separates from an ejection port (BTHJ ejection) is performed. On the other hand, when the image is one of high ejection duty, an ejection not communicating with the atmosphere as above (BUBBLE-JET ejection) is performed. As a result, an increase of ink mist due to satellites can be suppressed as a whole even if satellites are increased because of BTHJ ejection. When the ejection duty is high, generation of satellites themselves is reduced, thereby suppressing increase of ink mist.
