    摘要: An image forming apparatus enables a high-quality double-side printing of a transfer medium by one-pass method using a simple structure. A latent image is formed and developed on an image carrier (drum) in a process cartridge. A resultant toner image is transferred by a first transfer unit (roller) onto either an upper surface of the transfer medium or a first intermediate transfer body (roller) in a first transfer area. The toner image on the first intermediate transfer body is transferred onto a back surface of the transfer medium in a fourth transfer area via a second intermediate transfer body (belt) and a third intermediate transfer body (roller). The fourth transfer area is located downstream of the first transfer area along a transport path of the transfer medium.
