A liquid ejection head has a base plate with an actuator on an upper surface. Pressure chambers are formed in the actuator. A first common chamber connects to a first side of the pressure chambers, and a second common chamber connects to a second side. A nozzle plate is on an upper surface side of the actuator and has nozzles at positions corresponding to the pressure chambers. A supply hole is in the base plate and connected to the first common chamber. A discharge hole is in the base plate and connected to the second common chamber. A manifold is on a lower surface of the base plate. The manifold has a supply flow path for supplying liquid to the supply hole, a discharge flow path for receiving liquid from the discharge hole, and a temperature control flow path through which a temperature control liquid can flow.

A method for driving a liquid ejecting apparatus according to a thickening state of liquid in a nozzle determined by a thickening determination section. When the thickening state is a first state, a second flushing signal by which liquid is ejected from a nozzle is supplied a first number of times to the driving element without applying a micro vibration signal by which liquid is not ejected from a nozzle. When the thickening state is a second state in which viscosity of the liquid is higher than viscosity of the liquid in the first state, the second flushing signal that is different from a first flushing signal is supplied the first number of times after applying the micro vibration signal, and a first flushing signal by which liquid is ejected from a nozzle is supplied a second number of times to the driving element after applying the second flushing signals.
