In the photosensitive material processing apparatus, before the development step of supplying a developer to the exposed surface of the silver halide photographic light-sensitive material, a pre-processing solution is supplied to the exposed surface of the silver halide photographic light-sensitive material, and the contact of the developer is carried out. A photosensitive material processing apparatus characterized by comprising a pretreatment step for reducing corners.
