An image forming apparatus includes a recording head, a conveyance belt, a charger, a reverse passage, and an auxiliary conveyance roller. The belt is looped around at least two rollers to adhere a recording medium thereto by electrostatic force and convey the medium. The belt defines a normal conveyance area in which the medium is conveyed in a first direction. The reverse passage delivers the medium turned around in an area downstream from the belt in the first direction and sends the medium back again to a portion of the belt upstream from the head in the first direction. The reverse passage includes an opposite conveyance area of the belt in which the medium is conveyed in a second direction opposite the first direction. The auxiliary conveyance roller is disposed at least one of an entry part and an exit part of the opposite conveyance area.
