  • Patent number: 6457794
    Abstract: An ink jet recording apparatus is disclosed in which a bubble is created in ink by thermal energy generated in response to a drive signal applied to a heater, and the ink is ejected onto a recording material by expansion of the bubble. The recording apparatus includes a driving device and a changing device. The driving device applies a plurality of driving signals to the heater for each ink droplet ejection. The driving signals include a first driving signal for increasing a temperature of the ink adjacent the heater without creating the bubble, and a second driving signal after the first drive signal for ejecting the ink. An interval is provided between the first and second drive signals. The changing device changes a width of the first drive signal to adjust an amount of ejected ink. The interval is not shorter than 2.6 microseconds and the second drive signal has a constant width.
