ABSTRACT:
An image forming method for use with a photosensitive and pressure-sensitive material fed from a supply position to an exposure position by entrance-side and exit-side nip rollers disposed on opposite side of the exposure position in contact with an exposed material supporting roller. To eliminate sag from the sensitive material, the entrance-side and exit-side rollers are operated with a differential timing. To reduce the per sheet exposure time, a fresh segment of the photosensitive and pressure-sensitive material is fed to the exposure position immediately following each exposure operation.
