Abstract

An image forming apparatus of the present invention includes an intermediate transfer belt to which a toner image is transferred from an image carrier. A transfer roller contacts the intermediate transfer belt, forming a nip for image transfer. The transfer roller causes the toner image to be transferred from the intermediate transfer belt to a recording medium at the nip. A first and a second guide member cooperate to guide the recording medium to the nip. The end of the second guide member is positioned at the intermediate transfer belt side with respect to a line connecting a restriction point included in the first guide member and the inlet of the nip. This configuration causes a portion of the recording medium rearward of a portion entered the nip to bend in a convex configuration. The recording medium therefore surely remains in close contact with the intermediate transfer belt in a region where pretransfer is apt to occur.
