Abstract
An ink jet recording apparatus having a recording head for jetting ink droplets attached to a carriage 1 that reciprocates across the width of a recording medium and cap members 31, 32 for receiving ink droplets jetted for maintenance of the recording head during printing. To prevent banding and improve printing throughput, an ink discharge hole 35 having a window confronting the recording head is arranged in a nonprint region opposite to a side where the cap members 31, 32 are arranged and within a range of a locus of movement of the recording head. Discharging the ink from the cap members during printing for a single page can be dispensed with, and flashing is effected to the member 31 or 35 that is closer to the carriage.
