INK EJECTION INSPECTING DEVICE, INK EJECTION INSPECTING METHOD, STORAGE MEDIUM, INK EJECTING DEVICE, AND IMAGE FORMING APPARATUS

Abstract: an ink ejection inspecting device that inspects an ejection state of inks from a plurality of nozzles provided in an ink ejecting device includes: a head drive controller that applies an inspection voltage for an ink ejection inspection to each of the nozzles after a standby period ends, the standby period being from after an image forming period during which a drive voltage for image formation is applied to each of the nozzles ends until an effect of the application of the drive voltage to each of the nozzles converges; and a state determinator that determines an ink ejection state of each of the nozzles on a basis of residual vibration of each of the nozzles obtained by applying the inspection voltage.
