ABSTRACT:
An electrophotographic printer includes a fixing unit having a movable pressure roller, movable toward and away from a heat roller. The heat roller of the fixing unit is above a plane formed between a pair of discharge rollers and a tractor, so that the paper path between the tractor and the discharge rollers is straight when the pressure roller is retracted, and the paper path is bent when the pressure roller is moved to contact the heat roller. The paper path is bent by a guide member upstream of the pressure roller so that the path is not bent around the pressure roller itself.
