本発明は、ロール状に巻かれた感光材料に像様露光する

廃棄してしまう無駄があった。An image forming apparatus that performs imagewise exposure on a roll of photosensitive material has the advantage that it can be loaded with a photosensitive material of one size and cut into photosensitive materials of a plurality of sizes. On the other hand, in order to unwind the photosensitive material from the roll, the leading end of the photosensitive material protrudes from the roll, but since loading of the photosensitive material is usually done in a bright room, this protruding part is subject to light fogging. must be discarded. Therefore, conventionally, only the light-fogged portions are cut, or the light-fogged portions are cut to a size for imagewise exposure, and these are discarded through the photosensitive material processing process. However, with the former, clogging occurs frequently because the length is smaller than that of a normal one, and with the latter, unexposed portions are also discarded, which is wasteful.
