ABSTRACT:
An ink jet recording apparatus for forming a record by discharging ink from a recording head onto a recording material, has a tube pump for ink discharge recovery, by suction or pressurization, through deformation, with pressure rollers, of plural tubes communicating with discharge openings of the recording head. The timings of pressing of the tubes by the pressure rollers or the timings of release of the tubes from the pressed state by the pressure rollers are different from tube to tube.
