To provide a copying machine capable of permitting regular copying operation while controlling unauthorized copying operation.

Information that a true document is copied and outputted after three times recopying is stored in a master document original 10 as access control information. When the original 10 is read by the copying machine 1, a 1st false document 11 is outputted as a false information output matter. Furthermore, when the document 11 is read by the copying machine 1, a 2nd false document 12 is similarly outputted as a false information output matter. Then, when the document 12 is read by the copying machine 1, a regular document 13 where the content of the original 10 is printed is outputted. Thus, the regular document 13 having the correct content is outputted after three times recopying according to the access control information.
