Abstract
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.

An image forming apparatus that emits light from a light emitting element for a toner image forming region on a photosensitive member according to input image data and exposes the photosensitive member, the image forming apparatus comprising:
- a first clock output unit that outputs a clock to slightly emit light from the light emitting element for non-toner image forming region on the photosensitive member;
- and
- a control unit that based on the clock output from said first clock output unit, slightly emits light from the light emitting element to slightly exposure on the photosensitive member,
- wherein said first clock output unit outputs a clock for performing the slight exposure with a frequency diffused within a predetermined frequency range.
