Abstract

The ink jet recording apparatus of this invention comprises a means 67 for heating a record material to a predetermined temperature range at the position of recording, a recording head 41 for ejecting ink 46 from an ink ejection orifice 49 toward the record material to perform recording, the ink containing a substance having thickening properties when undergoing heat, and/or a substance having a cloud point for the heat; a means 69 for measuring the duration for which the recording head resides at the position of recording; and means for controlling the duration of residence in accordance with the properties of the ink to prevent the ejection function being impaired owing to the heating of the surroundings of the ink ejection orifice. This invention can provide an ink jet recording method which determines a rise in the temperature in the surroundings of the ink ejection orifice on the basis of the duration of residence of the recording head at the position of recording for the purpose of recording, and which performs control to suppress the temperature rise before the ejection function is interrupted.
