Abstract
Negatively charged toner particles on a record roller are attracted by a back electrode. When a first voltage is applied to a first electrode of a printed circuit board when this condition is present, the toner particles on the record roller are attracted more strongly so that they will jump toward a aperture in the printed circuit board. As the first voltage applied to the first electrode of the printed circuit board is turned off, a control section causes the potential difference between a second electrode and the back electrode to become smaller.
