Abstract:
1. An inkjet recording apparatus for performing recording by ejecting ink onto a recording medium using a plurality of heads, the apparatus comprising: said heads, each ejecting a different color ink and each having a plurality of heating means to eject the same color ink; a common support member on which said plurality of heads are arranged, said common support member conducting heat among said heads; obtaining means for obtaining temperature of a printing head unit including said common support member and said plurality of heads; a recording mode setting circuit for setting a head that is to be used for recording in a recording operation based on image data and a head that is not to be used for recording all the way through the recording operation based on the image data, from among said plurality of heads; and control means for controlling, when the obtained temperature of the printing head unit is lower than a first temperature, heating, not causing ejection, of all of the heads, controlling, when the obtained temperature of the printing head unit is higher than the first temperature and lower than a second temperature, heating, not causing ejection, of the heads set by said recording mode setting circuit to be not used for recording and stopping of heating, not causing ejection, of the heads set by said recording mode setting circuit to be used for recording, and controlling, when the obtained temperature of the printing head unit is higher than the second temperature, stopping of heating, not causing ejection, of all of the heads.
