To supply an image holding medium in a state where inclination and meandering are always hardly caused to an image processing mechanism for forming or reading an image, and to improve the throughput of an entire device.

This photographic processing device is provided with a carrying member 26 capable of moving while abutting on the trailing edge of photographic paper 2 supplied to an exposure part 14 performing the exposure processing of the image, and a pair of width regulating guides 28 extended substantially parallel with the moving direction of the member 26 respectively. By moving the member 26 abutting on the trailing edge of the photographic paper 2 in the carrying direction of the photographic paper 2, the photographic paper 2 is carried between a pair of width regulating guides 28. Thus, the inclination of the photographic paper 2 is corrected in a photographic paper carrying mechanism 13 and also the inclination and the meandering are not caused.
