摘要： An image forming apparatus comprising a laser beam radiating unit utilized as a light source, and an optical system that the surface of an original reflects a laser beam radiated from the radiating unit to project an image reflected from the original onto a photosensitive member. In this apparatus, an image is formed selectively in a print mode so that an image results from turning on and off the laser beam, in a copy mode that a copy of an original results from exposure of the photosensitive member to the laser beam reflected from the surface of an original or in a composite mode that a composite image is formed of a copy of an original and an image resulting from turning on and off the laser beam. Further, this apparatus comprises a projection lens unit for projecting an image reflected from an original onto the photosensitive member. The laser beam transmitting through the lens unit is scanned in the direction perpendicular to the main scanning direction, and altering the scanning speed and position of the lens unit results in various magnifications of an image.

摘要： An electrostatic latent image forming apparatus using a semiconductor laser 11 forms an image on a surface of a photoreceptor drum 15 by a laser beam modulated by an image signal while intensity of the laser beam is lowered by a reflection mirror 16 having a reflectance as low as 30%. The semiconductor laser 11 is driven by current obtained by adding bias current Iba to switching current Isw and a bias component out of an optical output level thereof is decreased by the reflection mirror 16 having the low reflectance. Therefore, an off-level optical output correponding to the bias current becomes lower than that in the case in which lowering of the intensity of the beam is not caused, and as a result, a "fogging" phenomenon or the like can be effectively prevented.
