Abstract

The present invention relates to a processing method for a silver halide color photographic material, which makes it possible to substantially reduce the amount of waste liquor and the pollution of the environments. In the process, the color photosensitive material is continuously developed, and the process is characterized in that all or a part of the overflow of a color developer being substantially free from benzyl alcohol is used as a part of a processing solution used in a process other than the color development process.
