Abstract:
An ink jet recording apparatus for recording an image by using a recording head to emit an ink by a heat generation of an electrothermal transducer, said apparatus performing recording onto a recording medium by relatively scanning said recording head and the recording medium, said apparatus comprising:driving means for driving said recording head in a recording mode selected from a plurality of recording modes, said recording modes including a first recording mode, for performing normal recording on a sheet of the recording medium and a second recording mode, for recording different portions of a single image onto a plurality of sheets, respectively, of the recording medium; supplying means for supplying a non-ejection heating signal to said electrothermal transducer so as not to eject the ink; selecting means for selecting conditions for supplying said non-ejection heating signal by said supplying means depending upon the recording mode; and control means for controlling said supplying means in accordance with the conditions selected by said selecting means depending upon the recording mode so that said supplying means is driven to reduce a difference between a head temperature at a start of a scan and the head temperature at an end of the scan when the second recording mode is selected.
