ABSTRACT:
A device for reproducing an image of an original by using photosensitive material and transfer material for receiving an image formed on the photosensitive material. The original is optionally scanned to produce an optical signal which represents an image of the original, and the photosensitive material is exposed in accordance with the optical signal from the scanner together with the movement of the photosensitive material in synchronization with the scanning. A developer device superposes the exposed photosensitive material on the transfer material and spreads a developer between the superposed photosensitive material and transfer material so as to reproduce the image on the transfer material.
