Stripping and developing device

摘要

A developing device for a photosensitive material consisting of a cover base laminated through the intermediary of a photosensitive layer to a support member develops the photosensitive material by stripping the cover base from the support member. The developing device employs a stripping roller consisting of the combination of a plurality of diametrically small separating rollers and a plurality of diametrically large brush rollers arranged in alternating side by side relation. A plurality of nip rollers contact respective ones of the separating rollers. The stripping roller is rotated in a direction opposite to the direction of movement of a photosensitive material and disposed in a photosensitive transporting passage with its brush rollers contacting the cover base surface. The cover base is stripped at its leading end from the support member by the brush rollers, and the leading end of the cover base is held for transportation between the separating rollers and the nip rollers.
