ABSTRACT:
In a photoreceptor web steering apparatus for a printer having a frame, a shaft is rotatably installed at the frame, and a guide roller for guiding the circulation of the photoreceptor web as a portion of the outer circumference of the guide roller which contacts the photoreceptor web, is rotatably installed at the shaft. A steering roller is arranged at the shaft next to the guide roller and includes a spacer installed to tilt at a predetermined angle with respect to the outer circumferential direction of the shaft, and a tilting shell rotatably installed on the outer circumference of the spacer and having the outer circumferential surface thereof being in contact with the photoreceptor web. The steering roller corrects a lateral slip of the photoreceptor web contacting the outer circumference of the tilting shell by changing the inclination direction of the tilting shell according to a pivot angle of the shaft. A driving unit installed between the frame and the shaft, controls the degree of pivot of the shaft.
