Claim:
1. A developing method comprising: horizontally holding an exposed substrate by a substrate holder; forming a liquid puddle on a part of the substrate which is stationary, by supplying a developer from a developer nozzle which is positioned above the part of the substrate and rotating the developer nozzle; rotating the substrate; spreading the liquid puddle on a whole surface of the substrate, by moving the rotating developer nozzle such that a supply position of the developer on the rotating substrate is moved in a radial direction of the substrate; bringing, simultaneously with the spreading of the liquid puddle on the whole surface of the substrate, a contact part into contact with the liquid puddle, the contact part being configured to be moved together with the developer nozzle and having a surface opposed to the substrate which is smaller than the surface of the substrate.
