An image recording apparatus includes a recording head having a plurality of
nozzles,
a carriage, a transfer mechanism, a driving mechanism, a detection mechanism which
optically detects an ink ejection state, and a controller. The plural nozzles are
divided into a plurality of nozzle groups. The controller makes an ejection timing
of each of the nozzle groups different from that of any other nozzle group. The
shifting time of the timing of each of the nozzle group is shorter than an ejection
cycle in image recording of each group.
