Abstract
In accordance with one embodiment, an image forming apparatus has a fixing section that transfers a toner image to a recording medium for printing in a printer section and then fixes the toner image, a decoloring section that heats and decolors a decolorable image printed on a recording medium for reuse with a color material of which the color is decolored if heated at a decoloring temperature, and a controller that enables the fixing section and the decoloring section to operate exclusively.
Claims10
An image forming apparatus, comprising:
- a fixing section configured to fix a toner image which is transferred to a recording medium for printing in a printer section;
- a decoloring section configured to heat and decolor a decolorable image printed on a recording medium with a color material of which the color is decolored if heated at a decoloring temperature;
- an instruction section configured to instruct the controller to carry out printing operation and decoloring operation;
- and
- a controller configured to prohibit, if the controller receives the instruction of the other operation different from the current operation which is one of a printing operation or a decoloring operation, carrying out the other operation different from the current operation.
