ABSTRACT:
An image forming apparatus includes a photosensitive drum, a laser diode, and an optical scanning system provided between said laser diode and the photosensitive drum, for scanning the recording medium by deflecting the light beam emitted from the laser diode to thereby form an image on the recording medium. The optical scanning system has one of predetermined optical characteristics different from each other. The apparatus further includes a memory which stores a plurality of sets of control data provided for the predetermined optical characteristics of the optical scanning system. The control data is used for controlling the laser diode. Further, the apparatus includes a control data selecting circuit which selects one of the sets of control data which relates to the one of the predetermined optical characteristics of the optical scanning system, and a controller for controlling the laser diode on the basis of image data and the selected one of the sets of control data.
