PROBLEM TO BE SOLVED: To provide a technique of decoloring a handwritten image of a low decoloration temperature at low energy consumption while maintaining an original image.SOLUTION: An image forming apparatus comprises: a printing function of forming an image by heating and fixing an unfixed toner image transferred onto a sheet by a heating part at a fixation temperature; a decoloration function of decoloring an image formed with a decolorable color material on a decoloration processing object sheet by heating the image by the heating part. The image forming apparatus comprises: a temperature sensor for detecting the temperature of the heating part; and a control part having a normal decoloration mode of controlling, on the basis of the temperature detection information of the temperature sensor, the temperature of the heating part in the range from a second temperature or higher, which is lower than the fixation temperature and a first temperature or lower, which is higher than the fixation temperature in order to execute the decoloration function.SELECTED DRAWING: Figure 4 |
