Abstract
An electrophotographic printer includes a transfer roller which rotates in contact with a cylindrical photoconductive drum. When print paper passes through a transfer point where the transfer roller is in contact with the photoconductive drum, a toner image on the photoconductive drum is transferred from the photoconductive drum to the print paper. A paper guide is disposed upstream of the transfer point with respect to a transport path of the print paper. The paper guide changes the direction of travel of the print paper so that the leading end portion of the print paper enters the transfer point in a direction substantially tangent to a circumferential surface of the photoconductive drum.
