PURPOSE:To prevent a stuck part by coloring powder from being formed in a non-image part and to prevent the winding of a paper in a fixing device by making a part which is at least closer to a leading edge side in a paper moving direction than a formed image the non-image part in the case of superposing and forming the image on the same side of the paper. CONSTITUTION:This device is provided with a paper supply means 55 which repetitively supplies the paper P to which the image is transferred without inverting from a surface to a back surface to an image carrier 27 after the latent image formed on the image carrier 27 is developed, and a control means 131 for actuating a non-image part forming means 121 so that a specified area at the time of transferring the developed image M to the surface of the paper may be the non-image part L when the means 55 acts. When the means 55 acts, the non-image part forming means 121 is actuated according to the command of the means 131 so that at least the part on the leading edge side in the paper moving direction A may be the non-image part L. Thus, the stuck part by the coloring powder does not exist at the leading edge part and the winding of the paper in the fixing device is prevented. |
