IMAGE FORMING APPARATUS AND PAPER PROCESSING METHOD USED THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide an image forming apparatus 1 capable of preventing erroneous use of reusable sheets by distinguishing between the reusable sheets and any other sheets of paper. SOLUTION: The image forming apparatus 1 picks up each one of sheets stacked in a tray 16, allows a detecting sensor 123 to detect whether a mark indicating a reusable sheet is assigned to the picked-up sheet, and accumulates the sheet in which the mark is not detected by the detecting sensor 123 in a cumulative unit 11. The image forming apparatus 1 erases a color of an image forming material by heating the sheet of which the mark is detected by the detecting sensor 123 and stores the sheet of which the image forming material is erased in a sheet cassette 10. The image forming apparatus 1 forms an image with the image forming material erasable by applying heat to the sheet stored in the sheet cassette 10. COPYRIGHT: (C)2009,JPO&INPIT
