PURPOSE:To prevent a scatter of an image at a guide member which receives a image supporting material from a carriage belt, by providing a self-discharge type electrostatics discharging means whose volume resistance is greater than the surface resistance. CONSTITUTION:A toner image on a photosensitive drum 17 is transferred to paper 3 and then carried electrically on the paper 3 as an unfixed image. The paper 3 carrying the unifixed image is carried in close contact with a carriage belt 15 by positive charge 5 on the reverse surface of the paper 3, received by a plate-like guide member 2 and then guided to a fixing member 1. Between the belt 15 and guide member 2, a roller 18 whose volume resistivity is greater than the surface resistivity is arranged to discharge unnecessary positive charge on the reverse surface of the paper through the surface layer of the roller 18 when the paper 3 passes over the turning roller 18. Consequently, any electric-field variation which may cause the disorder of the toner image does not occur, so that no disorder of the image occurs. |
