The image forming apparatus includes a BG exposure clock output section 305 which outputs a BG exposure clock f1 that slightly emits light from a laser for BG exposure toward a non-toner image forming region on a photosensitive drum 222 and a laser control section 308 which controls the laser so as to slightly emit light for BG exposure based on the BG exposure clock f1 output from the BG exposure clock output section 305. The BG exposure clock output section 305 outputs a clock for BG exposure with a frequency diffused in the range from f1min to f1max. |
