ABSTRACT:
A back electrode roller is connected to a back voltage applying circuit. When a sheet of paper is not located at a position corresponding to toner passage apertures, or when a non-printing portion of the sheet of paper is located at the position corresponding to the apertures, an inhibiting voltage for preventing attraction of the toner is applied from the back voltage applying circuit to the back electrode roller. Accordingly, even when the toner erroneously passes through the apertures, the attraction of the toner toward the back electrode roller can be prevented by the application of the inhibiting voltage.
