A liquid ejecting head unit includes head main bodies capable of ejecting liquid droplets from nozzle openings by applying pressure to liquid inside pressure generating chambers communicated with the nozzle openings. Liquid flow paths that are formed for the head main bodies connect the nozzle openings including the pressure generating chambers and storage members that store liquid to be supplied to the pressure generating chambers. Heating members are disposed in the vicinity of the liquid flow paths and heat the liquid flowing through the liquid flow paths. A control unit controls the heating members. Temperature detecting units detect temperatures of the liquid flowing through the liquid flow paths. The control unit controls the heating members based on the temperatures of the liquid, which are detected by the temperature detecting units and lengths of the liquid flow paths extending from the storage members to the head main bodies. |
