摘要： An endless belt is supported by a plurality of rollers. A transfer roller comes in contact with an outer surface of the belt to form a transfer nip. An auxiliary member makes contact with a recording medium on an upstream side of the transfer nip in a movement direction of the belt, to cause the recording medium to be in close contact with the outer surface of the belt. A bias applying unit applies to the auxiliary member a bias for electrostatically transferring a toner adhered to the auxiliary member to the outer surface of the belt.
