Abstract
An image forming apparatus includes a recording head, a conveyance belt, a reverse passage, and a charger. 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 with the medium facing the head. The reverse passage 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 and a bypass passage to guide the medium separated from the opposite conveyance area toward the normal conveyance area. The charger is disposed between the bypass passage and an outer surface of the belt to charge the outer surface of the belt.
