Abstract

An image forming apparatus includes an image forming unit, a fixing unit, first and second rotating members, and a discharge unit to discharge a recording material to an outside. The fixing unit fixes an image from the image forming unit onto the recording material. The first rotating member comes into contact with and guides the image bearing recording material, and is driven to rotate by conveyance of the recording material. The second rotating member comes into contact with the image bearing recording material more on a downstream side than the first rotating member in a conveyance direction of the recording material, guides the recording material, and is driven to rotate by conveyance of the recording material. The first rotating member does not perform swinging motion by coming into contact with the recording material, and the second rotating member performs swinging motion by coming into contact with the recording material.
