ABSTRACT:
An electrophotographic printer includes a photosensitive drum sensitized with first and second images to be printed and a sheet-feeding roller for supplying a sheet on which the images are printed. The photosensitive drum is sensitized by the first image for one side and the second image for the other side to be printed. The electrophotographic printer is comprised of first and second transfer rollers. The first transfer roller transfers and prints the first image, which is sensitized on the photosensitive drum, onto the one side of the sheet as the first transfer roller rotates while contacting the photosensitive drum. The second transfer roller transfers and prints the second image, which is sensitized on the photosensitive drum and transferred to the second transfer roller via the first transfer roller, onto the other side of the sheet as the second transfer roller rotates while contacting first transfer roller. The second transfer roller has a circumference equal to the total length of the sheet plus one half the circumference of the first transfer roller.
