Patent ID: 8466946

Claim:
An image forming apparatus comprising: an optical writing device including: a light source section composed of a plurality of light emitting elements arranged in a main scanning direction; an optical section including a plurality of coupled lenses to form an image on a light exposure face by gathering light emitted from the light emitting elements; and a storage section that stores first correction data that corrects the light intensity of the plurality of light emitting elements and second correction data that corrects an optical characteristic specific to the coupled lens, and a control section including a central processing unit configured to read out the first correction data and the second correction data from the storage section of the optical writing device, and to correct the first correction data based on the second correction data, wherein the second correction data includes block information to show a block where a light emitting element in which light intensity changes due to optical characteristic of the coupled lens is arranged; and the control section corrects the first correction data corresponding to the light emitting element included in the block based on the second correction data.
