イド装置。 A transfer system in which a front-side guide member and a back-side guide member that guide the transfer material to the surface of the image carrier are installed facing each other on the upstream side of a transfer charger that transfers the toner image formed on the image carrier onto the transfer material. The material guide device includes an actuating member that swingably supports the back side guide member and swings the back side guide member, and the actuating member is configured to swing when the transfer material enters the image carrier side. In this method, the back side guide member is swung in a direction in which the gap between the back side guide member and the image carrier becomes larger and the inclination angle of the back side guide member is gentler, so that the rear end of the transfer material is aligned with the image carrier. When moving away from the image carrier, the back side guide member is swung in a direction in which the gap between the back side guide member and the image carrier becomes smaller and the inclination angle of the back side guide member becomes steeper. Guide device.
