| description | PROBLEM TO BE SOLVED: To efficiently perform cleaning of an ejection face and to prevent a wiper or the ejection face from being partially deteriorated.SOLUTION: Sixteen grooves 109a and ten ones of the dummy grooves 109b extending in a main scanning direction are arranged on an ejection face 2a of a head so as to be parallel to each other in a sub-scanning direction. Ejection holes 108a for ejecting ink droplets are formed at bottom sections of the grooves 109a. A groove group X1 constituted by two ones of the grooves 109a, groove groups X2 to X4 each constituted by four ones of the grooves 109a and a groove group X5 constituted by two ones of the grooves 109a are arranged on the ejection face 2a sequentially from one side in the sub-scanning direction. Separation distances l1 to l4 between the corresponding adjacent ones of the groove groups X1 to X5 are larger than separation distances la to lk between the corresponding adjacent ones of the grooves 109a in each of the groove groups X1 to X5. The dummy grooves 109b are arranged at respective both the sides of each of the groove groups X1 to X5 in a sub-conveying direction. |
