Abstract
A recording apparatus which is provided with a plurality of heads accompanied with temperature rise in recording by the application of driving signals comprises means for detecting the temperature in apparatus to detect temperatures in the recording apparatus; means for obtaining the temperature of the recording head from an offset value set between the temperature in apparatus and the temperature of the recording head of the recording apparatus in accordance with the detection by the aforesaid means for detecting the temperature in apparatus; and means for controlling the driving signal to change the waveforms of the driving signal applied to the recording head. With the structure arranged as above, the offset temperature is varied in accordance with the operational situations to obtain the head temperature without detecting it directly, hence maintaining the discharging amount constantly in printing and between environments in order to suppress the variation of the density of images to be printed, and also, reduce the cost of the printer main body and that of the head significantly.
