Abstract: A liquid discharging apparatus, having a head, a reservoir section including a liquid reservoir chamber and an atmosphere communication path, a liquid flow path, a switching assembly, and a controller to control the switching assembly in a disconnecting process and the head in a discharging process after the disconnecting process, is provided. A volume of an air portion in the reservoir section is controlled to satisfy formulas: Vb=(Po+ΔP)*ΔV/ΔP and ΔP≤Pm. Po represents one atmosphere. AV represents a change in the volume of the air portion due to a change in a volume of the liquid caused by discharging a predetermined amount of liquid in the discharging process. AP represents a change in pressure of the air portion according to the change in the volume of the liquid in the discharging process. Pm represents a pressure resistance of menisci formed with the liquid in the nozzles.
