摘要
A process for recycling a spent hydroquinone developer for black-and- white photographic processing which comprises the steps of determining the volume of developer, optionally filtering the developer, and reconstituting the developer, whereby the spent developer is brought back to substantially the same composition and/or level of performance as fresh developer wherein the recycled developer can be used to process black-and-white photographic materials without adverse effects.
