Abstract
A transfer device includes image bearing members, an intermediate transfer belt, transfer members, a transfer bias applying unit and a bias control unit. The transfer bias applying unit applies a transfer bias to the transfer. The bias control unit causes a transfer bias having a polarity opposite to that of the toner to be applied to a first transfer member during the transfer process in the first transfer nip and during an adjacent transfer process which is the non-transfer process in the first transfer nip and the transfer process in a second transfer nip adjacent to the first transfer nip. Further, the bias control unit causes a transfer bias having the same polarity as that of the toner to be applied to the first transfer member during an adjacent non-transfer process which is the non-transfer process in the first transfer nip and the non-transfer process in the second transfer nip.
