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.
