A belt cleaning device includes a cleaning part positioned to be capable of being in contact with a surface of a belt, the cleaning part having a bias voltage and including a cleaning roller, and a metal roller. A scraping member is in contact with surface of the metal roller of the cleaning part. A conductive holding member holds the scraping member. A conductive member is disposed proximate to the cleaning part. A same potential keeping part includes at least a first connection member which is configured to electrically connect the cleaning part and the conductive holding member and to electrically connect the conductive holding member and the metal roller, and keeps the conductive member and the cleaning part at approximately the same potential.
