PROBLEM TO BE SOLVED: To stably obtain large injection quantity and to attain high speed processing. SOLUTION: Injection heads for injecting a processing soln. for a silver halide photographic sensitive material are arranged in a staggered form. When space of orifices provided in a same injection channel is defined as (d) and overlapping degree of orifices of a terminal injection channel 30 in adjoining injection heads is (z), (z) is set within a range: -0.1nd<=z<=1.5d. When (z) is between -3d to 0, especially large injection quantity can be stably obtained and thereby developing processing of high speed can be realized.
