PROBLEM TO BE SOLVED: To determine surfaces of sheets on which images can be re-recorded in an accurate and inexpensive manner.SOLUTION: In a digital copying device DU, a sheet on which re-recording possibility information that is determination information whether images can be re-recorded on an image recording surface is embedded as an embedded image and recorded as an image, is set on a document feed tray 11. Then, a document conveying part 12 conveys the sheet to a reading part of the body part 2; the reading part reads the image on the sheet; the body part 2 obtains the embedded image from the image on a predetermined surface of the sheet, and determines whether or not the predetermined surface is a re-recordable surface on which images can be re-recorded based on the re-recording possibility information of the embedded image; and if the predetermined surface is determined to be a re-recordable surface, the document conveying part 12 discharges the sheet to a document discharge tray 5 aligning the re-recordable surface on an upper side or a lower side.
