Abstract:
    The present provides an image-forming device by which a sufficient transfer efficiency can be achieved and a high-quality image can be outputted. A transfer roller 6 and an auxiliary roller 16 are installed inside the transfer belt 11. The transfer roller 6 is arranged abutting on the transcribing belt 11 within a conveying nip on which the photoreceptor drum 2 comes in contact with the transfer belt 11 and down stream from the position just below the photoreceptor drum 2, and the auxiliary roller 16 is installed down stream from a transfer nip on which the photoreceptor drum 2 comes in contact with the transcribing roller 6. The auxiliary roller 16 is positioned so that the angle, at which the transfer belt 11 releases from the photoreceptor drum 2, may agree with a tangential direction of the photoreceptor drum 2, and the transfer roller 6 is arranged within 1 mm before and behind the position where the transfer belt 11 releases from the photoreceptor drum 2.
