摘要： There is provided a decoloring device including a decoloring unit, a first sheet conveying unit, a pre-decoloring reading unit, a type determining unit, a second sheet conveying unit, a post-decoloring reading unit, a decoloring success or failure determining unit, and a determination criterion setting unit. The type determining unit determines the type of image on the sheet conveyed to the decoloring unit based on the reading result in the pre-decoloring reading unit. The post-decoloring reading unit reads an image on the sheet after the decoloring, which is conveyed by the second sheet conveying unit. The decoloring success or failure determining unit determines whether or not the decoloring in the decoloring unit is successful based on the reading result in the post-decoloring reading unit. The determination criterion setting unit sets a determination criterion in the decoloring success or failure determining unit, based on the type of image, which is determined by the type determining unit.

摘要： An image forming apparatus forms a stamp image with a stamp image developer having a color developing temperature at a color erasing temperature of an image forming developer, and forms a mask image with a mask image developer having a color re-developing temperature at a temperature not lower than a color re-developing temperature of the image forming developer. Accordingly, when a confidential document is color-erased, the stamp image develops color, and when the color-erased confidential document again develops color, it can not be read.

摘要： According to one embodiment of the present invention, an erasing apparatus includes a used sheet stacking tray, an image erasing unit, a stand-by tray, a stand-by tray driving unit, and an erased sheet stacking tray. The used sheet stacking tray stacks thereon a used sheet on which an image is formed using an erasable colorant of which a color is erased by a predetermined heating process. The image erasing unit performs the heating for the used sheet which is received one by one from the used sheet stacking tray and discharges an erased sheet from which the image formed on the used sheet is erased. The stand-by tray has a mechanism which can be driven in a predetermined direction and places thereon the erased sheet discharged by the image erasing unit. The stand-by tray driving unit drives the stand-by tray and enables the erased sheet to free-drop. The erased sheet stacking tray is disposed under the stand-by tray and stacks thereon the erased sheet which free-drops from the stand-by tray.
