Claim:
A transfer device comprising: an endless transfer belt that includes a first transfer portion, at which a developer image is transferred onto an outer periphery surface of the transfer belt, and a second transfer portion, at which the developer image is transferred onto a member to be transferred, the transfer belt moving toward the second transfer portion from the first transfer portion; a transfer member that, at the second transfer portion, sandwiches the member to be transferred between the transfer member and the transfer belt, and transfers the developer image to the member to be transferred; a tension application unit that includes a resilient member, and a tension application member that urges the transfer belt with resilient force of the resilient member and applies tension to the transfer belt; and a damping member that causes damping force to act on the tension application member when the tension application member moves in one of a direction in which the tension application member urges the transfer belt, or an opposite direction.
