ABSTRACT:
A laser beam control device related to the present invention includes an optical filter in the path of propagation of the laser beam from a laser light source to an image forming surface to form an image with the laser beam transmitted through the filter, and controls the transmittance of the filter based on the result obtained by detecting the intensity of the transmitted laser beam and comparing the detected value with a value of image density set by an operator.
