Abstract
A recording apparatus, which records on a recording medium by using a plurality of recording heads, includes: a carriage for moving the plurality of recording heads in a direction crossing the direction in which the recording medium is fed; and a control section which, when at least two of the plurality of recording heads are of the same recording color, performs recording by alternately using such recording heads for a predetermined number of lines, whereby the amounts of ink consumed by the plurality of recording heads are equalized to make the ink service lives of the recording heads substantially the same.
