SOLUTION: The image forming apparatus is equipped with the photosensitive drum 19, an optical scanning part 2, and an image surface illuminance measuring part 61. The optical scanning part 2 calculates a quartic approximate expression having measured values of illuminances on a plurality of image heights of the photosensitive drum 19 subjected to quartic approximation to a plurality of light amount set values at a laser. Next, an illuminance difference between the illuminance on an arbitrary image height of the photosensitive drum 19 and the illuminance on at least one or more other image heights is calculated for the plurality of light amount set values by using the quartic approximate expression. Then, an illuminance correction value is calculated on the basis of the illuminance difference, and a light amount of laser to be ejected from the semiconductor laser 12 is controlled on the basis of the illuminance correction value.

摘要： PROBLEM TO BE SOLVED: To optimize correction processing (registration correction processing or density correction processing) of an image forming condition and discharge processing of developer, or to optimize the discharge processing of the developer. SOLUTION: A state in which adjustment sequence is performed after a deep printing job 1, a light printing job 2 is performed thereafter, and discharge sequence, is performed after the light printing job 2, is shown in Fig. (a). In this case, the necessary printing JOB for the discharge sequence is performed before the adjustment sequence, and then the adjustment sequence and the discharge sequence are performed at the same time, as shown in Fig. (b). As a result, user's print waiting time is shortened. Since the developer discharged by the discharge processing of the developer is used in the correction processing of the image forming condition, consumption of the developer is decreased.
