Patent ID: 8174548

Claim:
An image forming apparatus comprising: a latent image carrier that moves in a first direction; an exposure head that includes a first imaging optical system, a second imaging optical system that is distanced from the first imaging optical system in the first direction, a light emitting element that emits a light to be imaged on the latent image carrier by the first imaging optical system and a light emitting element that emits a light to be imaged on the latent image carrier by the second imaging optical system; and a controller that is adapted to control a light quantity of the light emitting element that emits a light to be imaged on the latent image carrier by the first imaging optical system in accordance with an imaging characteristic of the first imaging optical system, wherein a position of the first imaging optical system and a position of the second imaging optical system are different in the first direction and are different in a second direction orthogonal to the first direction, the light emitting element that emits the light to be imaged on the latent image carrier by the first imaging optical system is different from the light emitting element that emits the light to be imaged on the latent image carrier by the second imaging optical system, and the imaging characteristic is an area of the light imaged on the latent image carrier by the first imaging optical system.
