The image forming apparatus, which is used for forming an image on the image receiving member such as a photographic paper or a electrophotographic photosensitive member. Each light signal emitting head turns on and off a plurality of light signal emitting elements extending in a main scanning direction in accordance with image data. The image receiving member is guided by a cylindrical guide roller with being adhered to the curving section of the guide roller at an exposure position. The light emergent from each light signal emitting head is changed its optical path at a dichroic prism or a half mirror and exposes the image receiving member linearly.
