Claim:
1. A developing method for developing a substrate, comprising: spinning the substrate with a spin holder; discharging a developer to the substrate from a plurality of exhaust ports arranged in a row on a developer feeder; causing a moving mechanism to translate said developer feeder in one direction extending to a center of the substrate in plan view while maintaining a direction of arrangement of said exhaust ports in said one direction, thereby to move said developer feeder between substantially the center and an edge of the substrate in plan view; and causing the developer discharged from said exhaust ports to impinge in separate streams on the substrate, and causing each of the separate streams to impinge spirally on the substrate, thereby to develop the substrate; wherein said spin holder and said moving mechanism are controlled to cause positions of impingement of adjacent streams of the developer to be close to each other, thereby to cover ranges of the substrate between loci of the positions of impingement with the developer spreading after impingement; a rearmost one of said exhaust ports, with respect to the direction of movement of said developer feeder, is moved while the substrate makes one spin to a position close in the direction of movement to a position of a foremost one of said exhaust ports at start of said one spin; a spinning speed of the substrate and a moving speed of said developer feeder are controlled to be constant, respectively, when causing the separate streams of the developer discharged from said exhaust ports to impinge spirally on the substrate, thereby to develop the substrate; said exhaust ports all move on one straight line in plan view; and wherein said spin holder and said moving mechanism are controlled, in a relational expression v×2π/ω=L+2r+m×P, where to maintain a relationship between said spinning speed ω of the substrate and said moving speed v of said developer feeder.
