PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of easily and simply forming a high quality image on both surfaces. SOLUTION: The image forming apparatus includes: a latent image forming means which forms a latent image on an image carrier; a developing means which develops the latent image on the image carrier, to form a toner image; a first transfer means which transfers the toner image on the image carrier onto the surface of a transfer material or a first intermediate transfer body; a second transfer means which transfers the toner image on the first intermediate transfer body onto a second intermediate transfer body; a third transfer means which transfers the toner image on the second intermediate transfer body onto a third intermediate transfer body; and a fourth transfer means which transfers the toner image on the third intermediate transfer body onto the rear face of the transfer material. The first intermediate transfer body and the third intermediate transfer body are like a roller, the second intermediate transfer body is like a belt and a fourth transfer section transferring the toner image onto the rear face of the transfer material is provided at the downstream from a first transfer section transferring the toner image onto the surface of the transfer material, on a conveying path for the transfer material.
