Ink jet recording apparatus that individually controls ink ejection from plural recording heads during a non-recording operation

An ink jet recording apparatus comprising:

• a recording means for recording, said recording means having a plurality of different groups of recording portions, each of said groups having an ink with a different property, each of said recording portions of said groups comprising:
• at least one ink outlet,
• at least one liquid passage communicating with said ink outlet and passing said ink and
• at least one ejection energy generating element communicating with said at least one liquid passage for generating energy for ejecting said ink through said ink outlet;
• refreshing means for performing a refreshing operation on each of said recording portions to refresh the ink in said liquid passage thereof by driving said ejection energy generating element to eject the ink when a recording operation of said apparatus is not performed, wherein all of said recording portions undergo the refreshing operation substantially simultaneously;
• and
• controlling means for controlling said refreshing means to provide a driving condition for said ejection energy generating element of each of said recording portions, wherein the driving condition during said refreshing operation for each of said plurality of different groups of said recording portions is predetermined independently based on said property of the ink.
