Abstract
A Cleaning fluid discharge openings capable of supplying a cleaning fluid is provided around a suction port mounted in opposition to a nozzle hole. A negative pressure generating source performs suction from the suction port to take out the cleaning fluid from the cleaning fluid discharge openings and to contact the cleaning fluid, thus taken out, with a neighborhood of the nozzle hole, and the cleaning fluid thus contacted is sucked and recovered from the suction port. A member of the suction port is made of a porous resin and the cleaning fluid discharge openings comprise pores formed on a surface of the porous resin. A cleaning fluid supplied to the porous resin is taken out from the pores formed on the surface of the porous resin to clean the neighborhood of the nozzle holes and to simultaneously clean the suction port as a wiping member.
