Patent ID: 10496024

Abstract:
An image forming apparatus according to an embodiment includes an image acquisition unit, a heating unit, a presence-or-absence-of-an-image determination unit, an image formation unit, a determination unit, and a heating control unit. The image acquisition unit reads an image on a sheet. The heating unit heats the sheet. Based on the image that is read by the image acquisition unit, the presence-or-absence-of-an-image determination unit determines whether the image is printed on the sheet. The image formation unit forms the image on the sheet using a decolorable toner that is decolorized by heating the sheet to a prescribed temperature and a non-decolorable toner that is not decolorized although the sheet is heated. The determination unit determines whether to supply power to the heating unit, depending on an instruction which the decolorable toner is decolorized and on determination by the presence-or-absence-of-an-image determination unit whether the image is printed on the sheet.
