An image generation apparatus (7, 77, 10) for generating an image by scanning a scanned face using laser beam includes a light source device (15) having at least one semiconductor laser; an optical deflection device (40) to deflect laser beam from the light source device (15) to the scanned face and a light detector (150); a light quantity adjustment device (30) including a member (32) disposable on a light path of the laser beam between the semiconductor laser and the optical deflection device (40) to adjust light quantity of the laser beam; an emission light intensity adjustment unit (500) to adjust emission light intensity of the semiconductor laser; and a controller (300) to set a first adjustment target value of the emission light intensity which is an adjustment target value of the emission light intensity and an adjustment target value of the light quantity when laser beam is deflected to the scanned face by the optical deflection device (40) based on target luminance of the image, and a second adjustment target value of the emission light intensity which is an adjustment target value of the emission light intensity when laser beam is deflected to the light detector (150) by the optical deflection device (40) based on an adjustment target value of the light quantity and detection sensitivity of the light detector (150).
