  • Image forming apparatus having decolorizing function and sheet conveying method in the image forming apparatus
    Patent number: 8874020
    Abstract: According to one embodiment, an image forming apparatus includes an image forming unit including an image carrier, a developing device for developing an electrostatic latent image formed on the image carrier using a developing agent containing a decolorable toner and forming a developing agent image, and a transferring and conveying mechanism and a fixing and decolorizing mechanism. In a decolorizing mode, the image carrier and a transfer member are separated in the transferring and conveying mechanism to secure a conveying path to prevent a transfer material from coming into contact with the image carrier.
