PROBLEM TO BE SOLVED: To provide a transfer method and a transfer device by which the center omission of a printed part is surely prevented while enhancing the image quality of a transfer image, and a double-sided printer using the same. SOLUTION: As the transferring method used at the time of transferring a toner image developed on a photoreceptive drum on paper inserted into a nip between a transfer belt and the drum, a nip width L (mm) between the photoreceptive drum and the transfer belt, the volume averaged grain size d (μm) of toner particles, resolution N (dot/mm) and the difference k of a circumferential speed ratio between the circumferential speed Vp (mm/s) of the photoreception drum and the circumferential speed Vt (mm/s) of the transfer belt are set so as to satisfy the relation of: 1,000×k×L/(π×d)>=1 and (k=|Vt/ Vp-1|). |
