a toner image carrier on which a toner image is carried; a transfer section that transfers the toner image on the toner carrier to transfer paper; a fixing section that fixes the toner image on the transfer paper; and the transfer section and the fixing section. In an image forming apparatus, the image forming apparatus includes a guide member disposed between the guide member and the guide member that guides the transfer sheet conveyed from the transfer unit to the fixing unit, the guide member being supported in a swingable manner, and and a fixing section guide member that is swingably supported independently of the transfer section guide member, and prevents the transfer section guide member from swinging in a direction away from the toner carrier. A stopper member for blocking within a certain range, and an urging member for urging the transfer section side guide member toward the toner carrier and urging the fixing section side guide member toward the fixing section, The image forming apparatus is further characterized in that the fixing section side guide member is brought into pressure contact with a member constituting the fixing section by the biasing force of the biasing member.
