Abstract

See full text

An image erasing apparatus according to an embodiment includes a scanner that reads an image printed on a sheet with decolorable colorant, the image including a first owner information. A decoloring unit decolors the image printed on the sheet. An input device receives a second owner information. A controller identifies the first owner information included in the image read by the scanner, and determines whether the first owner information corresponds to the second owner information. Based on the determination, the controller selectively controls the decoloring unit to decolor the image.
