a liquid application apparatus has : an application member that has an application surface applying a liquid onto a medium ; a holding member that abuts against the application surface of the application member so as to form a liquid holding space in which the liquid is held ; a liquid application device that rotates the application surface of the application member in such a manner that the liquid supplied from the holding member to the application surface is applied onto the medium ; a storage device that stores the liquid ; a first flow channel and a second flow channel that connect the storage device to the holding member ; a liquid movement device that causes oscillation of the liquid in the first flow channel , second flow channel and a flow channel including the liquid holding space to generate a flow of the liquid ; and a controller that controls the liquid movement device to generate the flow of the liquid caused by the oscillation in such a manner that a product which is generated from the liquid , has a higher viscosity than the liquid and adheres to interior walls of the first flow channel and the second flow channel , is solved in the liquid or collected in the liquid .
