  • Patent number: 8594545
    Abstract: An image-forming device includes an image carrier belt, a roller, a transfer material transporting member, and a transfer roller. The image carrier belt carries an image. The transfer material transporting member transports a transfer material. The transfer roller transfers the image to the transfer material at a nip. The transfer roller includes a concaved portion formed on a peripheral surface thereof and a transfer material gripping portion that grips the transfer material in the concaved portion. The transfer roller is in contact with the roller via the image carrier belt. A first interaxial distance between a rotation axis of the transfer roller and a rotation axis of the roller as the transfer material is gripped is larger than a second interaxial distance between the rotation axis of the transfer roller and the rotation axis of the roller as the image is being transferred onto the transfer material at the nip.
