PROBLEM TO BE SOLVED: To reduce a potential difference between a part where toner is transferred at secondary transfer and a non-image part where the toner is not transferred, and to prevent a transfer electric field from extending to the non-image part. SOLUTION: The device is provided with an image carrier PR having a surface on which a toner image is formed, and an intermediate transfer body B containing photoconductive material whose resistance value is reduced when the material is irradiated with light, and functioning as a high-resistance dielectric body when the body is not irradiated with light. Besides, the device is provided with a primary transfer device T1 for primarily transferring the toner image on the image carrier PR on to the intermediate transfer body B, a light irradiating/destaticizing device JK for destaticizing the intermediate transfer body B passing through a destaticizing area by the irradiation of light, a secondary transfer device T2 for secondarily transferring the primarily transferred toner image to a recording sheet S in a secondary transfer area Q4, a fixing device F for fixing the secondarily transferred image on the recording sheet passing through a fixing area Q5, and an intermediate transfer body potential adjusting device K for adjusting the potential on the intermediate transfer body B in a potential adjusting area Q6.
