PROBLEM TO BE SOLVED: To solve a problem that displacement members of head tanks cannot be detected by sensors disposed at an apparatus body side when recording heads are shifted in a sub scanning direction and disposed.SOLUTION: A recording head 11a and recording heads 11b to 11e are disposed at positions shifted in the sub scanning direction. In the apparatus body side, a first body sensor 301a, which detects the displacement member 205 of a head tank 12 of the recording head 11a, and a second body sensor 3011b, which detects the displacement member 205 of the head tanks 12 of the recording heads 11b to 11e, are provided. The recording head 11a and the recording heads 11b to 11e are collectively disposed in a main scanning direction. The recording heads 11b to 11e are disposed in the side where the first body sensor 301a and the second body sensor 301b are provided with respect to the recording head 11a. |
