ABSTRACT:
An image forming method of the present invention sequentially transfers toner images formed on image carrier to an intermediate image transfer body one above the other to thereby form a multicolor toner image. An image transfer roller faces the inside surface of the intermediate image transfer body for applying an image transfer bias when a toner image is transferred from the image carrier to the intermediate image transfer body. Rollers are positioned at both sides of the image transfer roller in the axial direction of the image transfer roller in order to control a nip width over which the image carrier and intermediate image transfer body contact each other during image transfer.
