ABSTRACT:
An electrostatic latent image forming apparatus using a semiconductor laser forms an electrostatic latent image on a surface of a photoreceptor by a laser beam emitted from the semiconductor laser while intensity of the laser beam is lowered by a low reflectance mirror which reflects a part of the laser beam and transmits the remaining laser beam. A light absorbing layer is disposed behind the low reflectance mirror for absorbing the laser beam passing therethrough. The semiconductor laser is driven by current obtained by adding bias current to switching current and bias component out of an optical output level thereof is decreased by the low reflectance mirror. Therefore, an off-level optical output corresponding to the bias current becomes lower than that in the case in which lowering of the intensity of the laser beam is not caused, and as a result, a "fogging" phenomenon or the like can be effectively prevented.
