Abstract
An embodiment includes a method of determining whether or not to perform a decoloring process on a sheet. A front position of a sheet fed in a sheet transport direction is detected. A presence or absence of an identification mark on a front portion of the sheet outside of an image forming area of the sheet is detected, after detecting the front position of the sheet. A determination is made of whether an image formed with decolorable color material is printed on the sheet based on whether an identification mark is detected on the front portion of the sheet. When the image formed with decolorable color material is determined to be printed on the sheet, the image is decolored.
