Image forming device having sheet conveyance device

An image forming device, for forming an image on a sheet, comprising:

• a pair of transport rollers rotatably supported so as to be rotatable in opposite directions, the pair of transport rollers for transporting the sheet therebetween by the rotation thereof so that the sheet exits from between the pair of rollers substantially aligned with a tangent plane of both of the pair of rollers;
• an elongated chute having at least a chute section for guiding the sheet after the sheet exits from between the pair of transport rollers, the chute section defining a chute plane which is divided space into a toner control electrode side and another side, the chute section having at opposite ends thereof a roller end and a toner control electrode end, the chute section being supported so that one of the pair of transport rollers is in confrontation therewith and another of the pair of transport rollers is in the toner control electrode side;
• a toner control electrode supported adjacent to the toner control electrode end of the chute section and supported in the toner control electrode side, the toner control electrode being formed with a plurality of apertures, the apertures having axes, the apertures being aligned on a surface of the toner control electrode so that their axes define an axis plane that is perpendicular to the chute plane and that is perpendicular to a plane defined by the surface of the toner control electrode, an angle formed between the axis plane and the tangent plane being less than 90.degree. and corresponding to a space that encompasses the toner control electrode end of the chute section;
• and
• a back electrode having an electrode tip, the back electrode being supported so that the electrode tip confronts the toner control electrode as separated by a space, the sheet being transported through the space as guided by the chute section.

• and
• a toner supply roller supported adjacent to the toner control electrode for supplying toner thereto and supported in the toner control electrode side, the toner supply roller being supported at a side of the toner control electrode opposite a side at which the back electrode is supported, the toner supply roller having an axis through which an axis plane passes, the axis plane being perpendicular to the chute plane, an angle formed between the axis plane and the tangent plane being less than 90.degree. and corresponding to a space that encompasses the back electrode end of the chute section.
