METHOD AND DEVICE FOR REMOVING IMAGE FORMING SUBSTANCE FROM IMAGE HOLDING BODY

摘要

PURPOSE:To provide a toner removing device capable of preventing the misuse or the erroneous discard of transfer paper on which unremoved image remains and the abuse of the unremoved image of a seal or a signature from occurring. CONSTITUTION:After toner peeling processing is performed by a liquid applying and toner peeling unit 6, the unremoved image (image by a seal or signing) remaining on the transfer paper 10 is detected by a CCD sensor 603a, and an identification mark (punched hole or mark O) is put on the transfer paper 10 detected as the one where the unremoved image remains by an identification mark putting unit 30. The transfer paper 10 already marked is automatically sorted by a sorting unit 40 and ejected to a paper ejection tray 501a or 501b. It is also good to provide a recognition unfeasible means for blurring the unremoved image (seal mark or signature) on the transfer paper or applying ink of the same color as the image or punching a hole on the image.
