The system of the present invention records a plurality of color separation images corresponding to an original color image simultaneously with determining whether the original color image conforms with any predetermined specific image, thereby assuredly preventing forgery of specific images such as bank notes. A color scanner (1) includes a scanner unit (10) and a bank-note identification unit (50). An invalidating lamp (71) is disposed in the vicinity of a record head (33) of the scanner unit (10). The invalidating lamp (71) can expose the whole surface of a recording film RF wound upon an output drum (17) to an exposure light. The bank-note identification unit (50) receives digital image signals Sy, Sk, Sm, and Sc input into a scanning head (19), determines whether an original OF is a bank note, and turns on the invalidating lamp (71) based on the recognition of the original OF as a bank note. This process effectively blackens the whole recording surface of the recording film RF to invalidate the record on the recording film RF.
