ABSTRACT:
A printer includes a transfer belt unit and an intermediate transfer belt. Two papers are fed into the printer one after another at a desired interval. 2nd and 4th images are transferred first onto the transfer belt unit and then onto back surfaces of respective papers. 1st and 3rd images are transferred by the intermediate transfer belt directly onto front surfaces of the respective papers. The 2nd and 4th images are formed on the transfer belt unit in such a manner that a distance between the two images on the transfer belt unit is set longer than the interval between the two papers.
