Claim:
1. A developing apparatus which is provided with a cup module including a substrate holding part configured to be rotated by a rotating mechanism and a liquid receiving cup surrounding the substrate holding part, and which performs development by supplying a developing solution to a substrate held on the substrate holding part, the apparatus comprising: a first cup module and a second cup module spaced apart from each other in a transverse direction; a first developing solution nozzle configured to wait in a standby position between the first cup module and the second cup module; and a first moving mechanism configured to move the first developing solution nozzle between the standby position and a processing position in which the developing solution is supplied to the substrate, wherein the first developing solution nozzle includes an ejection hole configured to eject the developing solution to form a liquid puddle on a surface of the substrate, the first developing solution nozzle including a contact portion that is smaller than the surface of the substrate and faces the surface of the substrate, and the first developing solution nozzle moves, together with a supply position of the developing solution, from one of a central portion and a peripheral edge portion of a rotating substrate to the other of the central portion and the peripheral edge portion in a state in which the contact portion makes contact with the liquid puddle, whereby the first developing solution nozzle spreads the liquid puddle on the substrate, the ejection hole of the first developing solution nozzle is formed to be opened on a lower surface of the contact portion, a standby part is installed in the standby position of the first developing solution nozzle, the standby part including a base portion having an upper surface formed as a cleaning solution guide surface portion, and the standby part is configured to fill a cleaning solution in a gap between the lower surface of the contact portion and the cleaning solution guide surface portion.
