PROBLEM TO BE SOLVED: To mitigate influence associated with difference of liquid ejection characteristics among nozzles which is caused by difference of driving characteristics of driver ICs.SOLUTION: Two driving ICs 52a1 and 52a2 are arranged separated by a space in a paper feeding direction on a left side of a scanning direction relative to a plurality of connection terminals 45a corresponding to a plurality of nozzles 15a arranged in the paper feeding direction. Among the plurality of connection terminals 45a, a plurality of connection terminals 62 positioned downstream of connection terminals 61a and 61b, which are positioned between the two driving ICs 52a1 and 52a2 in the paper feeding direction, are connected to the driving IC 52a1. Among the plurality of connection terminals 45a, a plurality of terminals 63 positioned upstream of connection terminals 61a and 61b in the paper feeding direction are connected to the driving IC 52a2. The connection terminal 61a is connected to the driving IC 52a2. The connection terminal 61b is connected to the driving IC 52a1. |
