Abstract

A toner image is formed on an image carrier using a toner supplied from a developing roller to which a controlled bias voltage is applied; the toner image is primarily transferred onto an intermediate transfer member; the toner image is secondarily transferred onto a recording sheet using a transfer voltage applied to the secondary transfer roller; and the bias voltage is applied to the secondary transfer roller as a cleaning voltage necessary for cleaning the secondary transfer roller; and the toner adhered to a circumferential surface of the secondary transfer roller is reversely transferred onto the intermediate transfer member.
