An endless belt, supported by the rollers, has a volume resistance within the range of 10.sup.9 to 10.sup.14 .OMEGA.cm. A photoreceptor is disposed adjacent to the endless belt. An endless belt charging device is disposed opposed to the photoreceptor in such a way that the endless belt is located between the endless belt charging device and the photoreceptor. An electrostatically charged toner supported on the surface of the photoreceptor is transferred to a print media. A guide member is disposed between the photoreceptor and the roller located upstream of the endless belt as viewed in the advancing direction of the endless belt. The guide device guides the advancing print media to bring the print media into contact with the endless belt.
