An ink jet recording apparatus can effectively extend its lifetime with
regard to disconnection without acceleration of deterioration of the
heater element with aging, and can avoid adverse effects owing to its use
environment, the deteriorated state of the heater element, scattering in
recording heads at manufacturing, and the like. Because deterioration of
recorded images caused by disconnection in heaters can be avoided, stable
image quality can be obtained. The ink jet recording apparatus has a
plurality of heater elements in a recording head thereof, for ejecting
ink by heating of the heater elements, and includes a control unit for
executing driving control of the heater elements. The same heater element
is driven for recording under different driving conditions, independently
of recording data.
