Abstract
According to one embodiment, an image forming apparatus includes an image forming section, a fixing device, and a control section. The image forming section forms images on a sheet with a recolorable decolorable colorant and an undecolorable colorant. The fixing device heats the sheet to fix the recolorable decolorable colorant and the undecolorable colorant on the sheet. The control section performs temperature control for the fixing device and fixes the recolorable decolorable colorant and the undecolorable colorant on the sheet at temperature higher than decoloring start temperature of the recolorable decolorable colorant to thereby fix the recolorable decolorable colorant on the sheet in a decolored state and fix the undecolorable colorant on the sheet in a colored state.
