A liquid ejecting device includes a liquid ejecting head which has a nozzle formation face on which nozzle orifices for ejecting liquid drops are formed and a controller which performs a recovery operation for removing a liquid having a changed liquid property. The recovery operation is performed by using at least a flushing mode in which liquid drops are ejected in a state that the nozzle formation face is sealed. The controller selectively performs a plurality of flushing modes which are set in accordance with degrees in change of a liquid property of the liquid drops being at and near the nozzle orifices. The degrees in change of the liquid property of the liquid drops are determined by a relation between an accumulative time that the nozzle orifices are left in a sealing state and an accumulative time that a liquid ejection is executed. A high flushing mode of the flushing modes for removing the liquid having a high degree in change of the liquid property has a first flushing mode which is performed at a first time and second and subsequent flushing modes which is performed at a second and subsequent time. The number of liquid drops ejected in the first flushing mode is greater than the number of liquid drops ejected in the second and sequent flushing modes.
