ABSTRACT:
In a recording sheet conveying device comprising: a dielectric sheet which moves at a predetermined speed while electrostatically retaining a recording sheet on the outer surface thereof; a charger positioned on the side of the inner surface of the dielectric sheet, to induce electrostatic attraction forces between the dielectric sheet and the recording sheet; and a deflector roll having an electrically conductive layer as an outer surface thereof, the deflector roll being confronted with the charger and adapted to push the recording sheet against the dielectric sheet, the number of electric charges provided by the charger is so adjusted that electrostatic attraction forces acting on the rear end portion of the recording sheet are weaker than those acting on the front end portion of the recording sheet, whereby the recording sheet is prevented from being wrinkled when electrostatically retained on the dielectric sheet.
