Reversal processing methods for black and white photographic light-sensitive materials

In a method for reversal development processing for an imagewise exposed black and white silver halide photographic light-sensitive material which comprises a first development, a development stopping, a bleaching, a second exposure or chemical fogging and a second development with a developing solution, the improvement which comprises bleaching the light-sensitive material with a bleaching solution containing an oxidizing agent which converts a silver image which is present into a water-soluble silver salt, in the presence of at least one bleach-accelerating agent which is incorporated into the development stopping solution represented by the following formulae (I) to (III) and (V) to (VIII):
