    摘要： An image forming apparatus includes an image bearing member, a latent electrostatic image forming unit, a developing unit, an intermediate transferring unit which has an intermediate transfer belt and a plurality of rollers supporting the intermediate transfer belt, and a transfer fixing unit. The transfer fixing unit has a transfer fixing belt, a plurality of rollers supporting the transfer fixing belt, a heating member, and a pressurizing member forming a transfer fixing nip with the transfer fixing belt. A first roller, which is one of the plurality of rollers supporting the intermediate transferring belt, is opposite to a second roller, which is one of the plurality of rollers supporting the fixing transfer belt. The first roller and the second roller form a transfer nip between the intermediate transferring belt and the fixing transfer belt. The diameter of the first roller is smaller than the diameter of the second roller.

    摘要： An image forming apparatus includes an image bearing member to bear an electrostatic latent image on the surface thereof, a transfer-fixing member disposed adjacent to the image baring member, including a transfer surface onto which the toner image is transferred from the image bearing member, a first pressure member to meet and press against the transfer-fixing member to form a nip therebetween, a heating member to heat a recording medium, provided upstream of the nip in a direction of transport of the recording medium, and a transport guide member to change a contact area of the recording medium and the heating member in accordance with a thickness or a resilience of the recording medium. When the recording medium passes the nip, the toner image is pressed and fixed on the recording medium.
