PURPOSE:To obtain an image with high quality by inclining and placing an image carrier surface against an exposure incidence for forming an image. CONSTITUTION:By providing a carrying base 24 so that the left side goes down and also providing a photosensitive body supporting roller 22 in the lower part, the peripheral surface of a photosensitive body 20 is inclined in the left direction and an angle theta is set to 89.7 deg. or 45 deg.. In such a state, when a laser beam shown by a one point chain line is reflected by the peripheral surface of the photosensitive body 20, its reflected light travels in the direction shown by a broken line and does not go into a dust-proof glass 15 being an exit window of the laser beam, and accordingly, this device is constituted so that a back flow cannot be executed to a light source of the laser beam, namely, a laser device. In such a way, a strong miscellaneous light does not go into the laser device, an output of the laser beam is high and stable, and an image of good contrast can be formed on the peripheral surface of the photosensitive body 20. |
