Abstract
An image forming apparatus includes an image carrier having a curvature in a first direction; and an exposure head including a first light emitting element that emits a light having a wavelength λand a light having a wavelength λ, a first optical system that converges each of the light emitted from the first light emitting element onto the image carrier, a second light emitting element, and a second optical system that converges a light emitted from the second light emitting element onto the image carrier, wherein a position at which the first optical system converges each of the light and a position at which the second optical system converges the light are different from each other with respect to the first direction.
