Abstract
A laser beam printer which forms a latent electrostatic image on a photoreceptor with a laser beam to perform an image recording operation, including scanning density switching means for selectively switching a scanning density of the laser beam on the photoreceptor within a plurality of values, and parameter switching means for selectively switching a parameter other than the scanning density of the laser beam within a plurality of values in the steps of producing a print. The parameter is, for example, a quantity of the laser beam, a width of the laser beam for one pixel in the main scan direction, or the like. A switching operation of the parameter switching means is controlled in accordance with a value of the scanning density selected by the scanning density switching means.
