    • 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.
    • 图像形成装置包括记录头,输送带,充电器,反向通道和辅助输送辊。 皮带围绕至少两个滚子环绕,以通过静电力将记录介质粘附到其上并传送介质。 皮带限定了在第一方向上传送介质的正常输送区域。 反向通道在第一方向上在皮带下游的区域中传送介质,并将介质再次返回到头部沿着第一方向的上游的一部分。 反向通道包括带的相对的传送区域,其中介质沿与第一方向相反的第二方向传送。 辅助传送辊设置在相对传送区域的入口部分和出口部分中的至少一个上。
