Abstract: PURPOSE:To prevent the sticking of oil to an image carrier and to form an excellent image by separating a transfer means from a transfer material carrier at least in a period that a region after being carried by the transfer carrier passes a transfer position without carrying the transfer material. CONSTITUTION:On a paper sheet carried up to a transfer nip part, a successive transfer is performed and while the toner of the final color is transferred, the paper is not separated even if its leading edge part is carried up to a separating part, but the rotation is executed as the paper is carried on a transfer drum 5a. After the transfer of the final color is entirely completed, the rotational speeds of the transfer drum 5a and a photoreceptor drum 1 are reduced. And, the paper is separated simultaneously with the first surface with timing that the leading edge of the paper reaches the separating part again and a transfer brush 5b is separated from the rear of a carrying sheet 5f with the timing that a part after the leading edge of the paper exists reaches the transfer part, during the same period as the separation. By this constitution, the transfer brush 5b is separated from the rear of the transfer sheet while the region of the carrying sheet 5f having carried the paper passes the transfer part without carrying the transfer paper.
