A photographic light-sensitive material having a support having a thickness of from 160 to 225 .mu.m is processed with an automatic developing apparatus, in which at least one of rollers of a developing part, a fixing part and a rinsing rack part of the automatic developing apparatus has a surface mainly containing a nonpolar polymer substance and having a center line surface roughness (Ra) of 20 .mu.m or less. By using the automatic developing apparatus, dusts generated in the apparatus can be easily removed with a cleaning film.
