Patent ID: 11966173
Assignee: TOSHIBA TEC KABUSHIKI KAISHA
Field: Optics (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. An image forming apparatus equipped with an exposure device including a plurality of light emitting points, comprising:
a photoconductor on which a latent image of an image to be formed is formed on the surface thereof by light emitted from the plurality of light emitting points of the exposure device; and
a processor configured to control the light emission of each of the plurality of light emitting points of the exposure device based on the image to be formed, wherein
the processor
calculates 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 to be formed, and
corrects a light output of each of the plurality of light emitting points by the fourth correction coefficient.
