  • Image forming apparatus that controls light intensity for exposure
    Patent number: 10915037
    Abstract: An image forming apparatus includes: an image carrier; a light source configured to emit light for exposing the image carrier; a controller configured to control a light intensity of the light source; a reference current generator configured to generate a reference current based on a target light intensity of the light source, the target light intensity being set by the controller; a correction current generator configured to generate a correction current for correcting the reference current based on an amount of correction that is set by the controller, and on the target light intensity; and a driver configured to drive the light source using a drive current that corresponds to a difference between the reference current and the correction current.
