Claim 10:
11. A method for an image forming apparatus equipped with an exposure device including a plurality of light emitting points, comprising:
forming on a surface of a photoconductor a latent image of an image by light emitted from the plurality of light emitting points of the exposure device;
controlling the light emission of each of the plurality of light emitting points of the exposure device based on the image;
calculating a fourth correction coefficient by changing a third correction coefficient, which is calculated based on a first correction coefficient for correcting a first physical quantity related to an exposure condition of the photoconductor by the light emitting points, and a second correction coefficient for correcting a second physical quantity related to the exposure condition of the photoconductor by the light emitting points and is between the first correction coefficient and the second correction coefficient, based on a light emission time set according to a gradation of the image; and
correcting a light output of each of the plurality of light emitting points by the fourth correction coefficient.
