Abstract
A recording apparatus includes a heat generating element which is driven to generate heat and thereby effect image recording on a recording medium. In the apparatus, a reference voltage for driving the heat generating element is set, and a driving voltage based on the reference voltage is output. A signal is detected which corresponds to an amount of electric power supplied to the heat generating element during image recording. A control unit controls the outputting of the driving voltage based on the amount of electric power, and adjusts the energy to be applied to the heat generating element.
