Ink jet recording apparatus and ink jet recording method
摘要:
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.
