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.

There is provided a decoloring device including a decoloring unit, a first sheet conveying unit, a second sheet conveying unit, a reversing and conveying unit, a manual feed tray, and a manual discharge tray. The reversing and conveying unit is disposed adjacent to an outer wall of the decoloring device in relation to the first sheet conveying unit, and conveys once again the sheet, which is temporarily brought into the second sheet conveying unit after being decolored by the decoloring unit and is switch-back conveyed, to the first sheet conveying unit. The manual feed tray is provided at an outer wall side of the decoloring device adjacent to the reversing and conveying unit. The manual discharge tray is provided at a position of the outer wall side of the decoloring device adjacent to the reversing and conveying unit.

An image processing device has an image forming portion, a heating portion and a supplying portion. The image forming portion forms an image on a sheet. The heating portion heats the sheet on which the image is formed by the image forming portion at a predetermined temperature, to thereby fix the image on the sheet. The supplying portion supplies the sheet on which an image is fixed previously. Further, the heating portion heats the sheet on which the image is fixed and which is supplied from the supplying portion at a temperature higher than the predetermined temperature to thereby remove the image.
