To attain a long service life of a wiper member and to suppress the generation of faulty discharge of droplets due to wasted materials sticking to a nozzle.

A plurality of nozzles 8 are opened to an ink discharge face 2a of an inkjet head. The ink discharge face 2a is wiped out by moving a wiper blade 201 in a wiping out direction by a moving mechanism with the contacting face 202 of the wiper blade 201 in contact with the ink discharge face 2a. In this case, a groove 203 is formed at the distal end of the wiper blade 201 such that a non-contacting zone 202a in no contact with the open end of the opposite nozzles 8 is formed.
