Claim Text:
1. A transfer device, comprising: an image carrier to carry a toner image thereon; a transfer roller to form a transfer nipping portion in contact with the image carrier and transfer the toner image carried on the image carrier onto a recording medium entering the transfer nipping portion; and a moving unit to move the transfer roller between a nip formation state in which the transfer roller forms the transfer nipping portion in contact with the image carrier and a separated state in which the transfer roller is separated from the image carrier, wherein in a contact operation of bringing the transfer roller into contact with the image carrier via the recording medium, the moving unit moves the transfer roller toward the image carrier at a moving velocity slower than that in a pressing operation of generating a predetermined nipping pressure by further moving the transfer roller toward the image carrier after the contact operation, and the recording medium enters the transfer nipping portion in the contact operation.
