摘要：
Rollers including a tension roller are arranged in parallel. A pair of supporting members supports both ends of the rollers. A transfer belt is supported by the rollers. A biasing member applies a tension to the transfer belt by biasing the tension roller in a predetermined direction. The tension roller is movably supported in a straight-line direction. The biasing member is arranged in an area surrounded by the supporting members and the transfer belt in a direction of traversing from one supporting member to other supporting member.
