ABSTRACT:
An ink jet recording apparatus is equipped with an ink suction pump which performs discharge recovery treatment for maintaining the ink within the discharge port under a predetermined state by sucking ink from the discharge port of a recording head. The ink suction pump has a cylinder and a piston moving in a reciprocal fashion relative to the cylinder therein and performs suction of the ink and discharge of the sucked ink as accompanied with the reciprocal movement. An annular contact portion forming a route for the discharge, which, in the actuation according the suction, blocks the route for discharging the ink, and maintains a predetermined interval by separation in the actuation according the discharge. The annular contact portion is provided at either the end surface of the piston or the end surface of the pushing member which pushes the end surface in the actuation of the suction.
