a print head including a plurality of nozzles configured to eject droplets onto a print medium;
a control unit configured to control driving of each of the plurality of nozzles to eject the droplets; and
an inspection unit configured to inspect whether or not each of the plurality of nozzles is able to eject the droplets normally by driving the print head by the control unit,
wherein in a case where the inspection unit inspects one target nozzle among the plurality of nozzles, the control unit drives the target nozzle and one or more neighboring nozzles arranged near the target nozzle such that (1) the control unit drives the target nozzle and the one or more neighboring nozzles simultaneously, and (2) after the simultaneous driving, the control unit drives the target nozzle alone.
