1. A liquid ejecting apparatus comprising:
a plurality of ejecting portions driven by a driving signal and configured to eject a liquid to form an image on a medium by using the liquid;
an acquisition unit configured to acquire a first vibration information and a second vibration information, the first vibration information being an information on a vibration generated in an inspection target ejecting portion out of the plurality of ejecting portions in a first detection period included in a first period in which the liquid ejecting apparatus forms a first printed image on the medium, and the second vibration information being an information on a vibration in generated in the inspection target ejecting portion in a second detection period corresponding to the first detection period, the second detection period being included in a second period that starts after completion of printing of the first printed image on the medium in the first period, in which the liquid ejecting apparatus forms a second printed image related to the first printed image on the medium; and
an inspection unit configured to inspect a state of ejection of the liquid from the inspection target ejecting portion based on the first vibration information and the second vibration information.
