A toner image forming device for forming, on the basis of input image signals, a toner image on a recording material with a first toner and a second toner having the same hue as the first toner and a density different from that of the first toner. A fixing device for heating and fixing the toner image on the recording material. A selecting device for selecting either one of a first mode and a second mode, wherein a glossiness level of a toner image outputted in response to the input image signals having the same density level is higher in the second mode than in the first mode. A changing device for changing, in response to selection of said selecting means, a fixing condition of said fixing means and a use ratio of the second toner at the input image signal corresponding to a predetermined density level.
