Abstract:
1. A method of transferring toner images to both sides of a recording medium, said method comprising the steps of: causing surfaces of a first and a second intermediate image transfer body to endlessly move while forming a nip in contact with each other; transferring a first toner image formed on an image carrier to said second intermediate image transfer body via said first intermediate image transfer body; transferring a second toner image formed on said image carrier to said first intermediate image transfer body; and transferring, when a recording medium nipped by the nip is being conveyed toward a side downstream of said nip in a direction in which said surfaces move, said first toner image from said second intermediate image transfer body to a first side of said recording medium and transferring said second toner image from said first intermediate image transfer body to a second side of said recording medium; wherein said second intermediate image transfer body is less deformable than said first intermediate image transfer body in a direction of thickness.
