Abstract
Provided is an image forming apparatus including: a latent image carrier, on which a latent image is formed; an exposure head that includes a first light-emitting element and a second light-emitting element that is disposed in a direction in which the latent image container corresponding to the first light-emitting element is moved; and a control unit that changes over and performs a first latent image forming operation, in which the latent image is formed on the latent image container by using the first light-emitting element, and a second latent image forming operation, in which the latent image is formed on the latent image container by using the second light-emitting element, wherein the control unit controls a first light emission timing of the first light-emitting element in the first latent image forming operation and a second light emission timing of the second light-emitting element in the second latent image forming operation to be different from each other.
