Abstract

PURPOSE: To curtail the cost of a cleaning device by electrifying a residual matter on a transfer intermediate body to the polarity opposite to the electrification charge of a photosensitive body.
CONSTITUTION: A toner image of three colors is transferred onto a transfer intermediate body 24 is transferred by a transfer device 24b to a form fed from a feed paper part 3, and its form is peeled off by a peeling device 24c and fixed by a fixing part 4. On the other hand, even after the toner image is transferred to the form, the toner image remains behind on the intermediate body 24. Its residual toner and dust, etc., which is adhered to the intermediate body 24 are electrifed to negative by an electrifier 24d. When the intermediate body 24 is transferred the toner image and transfer the toner image to the form, the intermediate body 24 is electrified to positive by the transfer device 24a and 24b, but becomes a roughly neutralized state by the peeling device 24c and the electrifier 24d, and only the toner and the residual matter such as dust, etc., are electrified to negative. Also, in this case, a photosensitive body 2 is also electrified to positive by an electrifier 21, and the residual matter electrified to negative is transferred to the photosensitive body 2. The residual matter transferred to the photosensitive body 2 is removed by a cleaning device 25, and the photosensitive body 2 is destaticized by a destaticizing lamp 26.
