Abstract

See full text

A decoloring device according to an embodiment includes a decoloring unit that erases a first image formed with erasable colorant on a first side of a sheet and a second image formed with erasable colorant on a second side of the sheet. A reading unit reads the first and second sides of the sheet and determines whether the first side and the second side are reusable. A single-side reusable paper tray stacks the sheet if the reading unit determines that only one of the first and second sides is reusable. A marking unit adds a mark to the one of the first and second sides that is determined to be not reusable when only one of the first and second sides is determined to be reusable.
