ABSTRACT:
An image forming device for forming an image on a sheet. A pair of transport rollers are provided for transporting the sheet by their rotation so that the sheet exits from between the pair of rollers while substantially aligned with a tangent plane of both of the pair of rollers. An elongated chute is provided for guiding the sheet after the sheet exits from between the pair of transport rollers. The chute is supported so as to intersect the tangent plane to cross from one side of the tangent plane to another in the direction followed by the sheet. A toner control electrode is supported adjacent to the chute at its end opposite the transport rollers. A back electrode with an electrode tip is supported so that the electrode tip confronts the toner control electrode as separated by a space. The sheet is transported through the space as guided by the chute.
