The laser printer forms an image on a photosensitive drum and reads a manuscript using the duplex structured hologram disk. The laser printer comprises a feeder for ffeding manuscripts, an image former for forming an image on a photosensistive drum using laser beams, a reader for reading a manuscript, an optical unit for deflecting the laser beam to the image former and the reader using the hologram disk, and a duplication unit for print the image on the photosensitive drum. The image former includes a reflecter for reflecting the laser beam divided by a beam splitter, a condensing lens for condensing the reflected laser beam, a reflector for reflecting the diffracted laser beam, a convex reflector for compensating the bending of the scanner beam, and a shutter for switching the laser beam.
