ABSTRACT:
An image forming apparatus is provided. The image forming apparatus includes a light emitter which emits light; a drive section which drives the light emitter according to a control signal; a light amount detection section which detects an amount of light which is emitted from the light emitter; an analog to digital converter which converts the amount of light into a digital value; a feedback controller which controls the control signal based on the digital value and a reference value, and outputs the control signal to the drive section; and a setting change section which sets a change unit used by the feedback controller to control the control signal.
