IMAGE FORMING APPARATUS AND METHOD FOR CONTROLLING IMAGE FORMING APPARATUS, WHICH INCLUDES FIXING AND DECOLORIZING SECTION

摘要

An image forming apparatus includes a count section configured to count time during which no image forming is performed and a control section configured to allow heating of a heat generating section at temperature for decolorizing after the time counted by the count section reaches the a predetermined threshold time.

1. An image forming apparatus comprising:
an image forming section configured to form an image on a medium with a decolorizable toner; a fixing and decolorizing section configured to fix the image formed on the medium and to decolorize the image on the medium selectively; a heat generating section configured to heat the fixing and decolorizing section to a first temperature during the fixing and to heat the fixing and decolorizing section to a second temperature higher than the first temperature during the decolorizing; a count section configured to count time during which the image forming section doesn't perform an image forming after the image forming on the medium is finished through the fixing; and a control section configured to heat the fixing and decolorizing section at the second temperature after the time counted by the count section reaches a predetermined threshold time, wherein, the control section also heats the heat generating section at the first temperature or a third temperature lower than the first temperature to keep energizing the fixing and decolorizing until the time counted by the count section reaches the predetermined threshold time.
