摘要： A belt carrying device includes supporting rollers, an endless belt supported by the supporting rollers, and guiding members provided on the endless belt. The endless belt is rotated by rotation of the supporting rollers. An outer peripheral surface of the endless belt is in contact with a cleaning member. The guiding members are provided on those projecting areas of the endless belt, which project in an axial direction of the supporting rollers from both end surfaces of the supporting roller. A guiding member suppresses meandering of the endless belt by coming into contact with an end surface of the supporting roller. Formed on the end, surfaces of at least one of the supporting rollers are projecting sections and groove sections, which are rotated around a rotation axis of the at least one of the supporting rollers in response to rotation of the at least one of the supporting rollers.
