Zusammenfassung:An imaging apparatus includes a transfer belt, a transfer roller, a conductive roller, and a power source. The transfer roller includes a metal shaft electrically floating during an imaging operation. The conductive roller has an electrical resistance lower than an electrical resistance of the transfer roller. The power source is electrically connected to the conductive roller, and the power source includes a first supply path to supply a first electrical bias to the conductive roller during an imaging operation and a second supply path to supply a second electrical bias to the transfer roller during a cleaning operation.
