Abstract:
An image forming apparatus may include a first transfer section for transferring a toner image, formed on an image carrier by utilizing a charging section, an exposing section and a developing section, onto a belt shaped intermediate transfer member; and a second transfer section for transferring the toner image on the intermediate transfer member onto a recording material by applying an electric field between a second transfer roller being provided outside the intermediate transfer member and a backup roller being provided inside the intermediate transfer member, the second transfer roller and the backup roller sandwiching the intermediate recording member and the recording material. The second transfer roller may be grounded and a bias voltage may be applied to the backup roller, and a second charging section for charging a surface of the second transfer roller with a predetermined polarity may be included.
