ABSTRACT:
An electrophotographic printer including a backup roller for supporting a photosensitive belt, a pressing roller for pressing a supplied paper, a transfer roller selectively contacting or being separated from the backup roller and the pressing roller while moving forward or backward between the backup roller and the pressing roller, and a driving unit for moving the transfer roller forward and backward. The transfer roller, the backup roller and the pressing roller are easily aligned with accuracy, and the impacts occurring when the rollers contact each other and are separated from each other are made less severe.
