An image forming apparatus includes: a latent image bearing drum that rotates and on which a latent image is formed; an exposure head having a first light-emitting element that exposes a first region of the latent image bearing drum and a second light-emitting element that exposes a second region of the latent image bearing drum; a storage unit that stores first speed-related information relating to the rotational speed of the first region of the latent image bearing drum and second speed-related information relating to the rotational speed of the second region of the latent image bearing drum; and a light-emission timing adjustment unit that adjusts the timing of the light emission of the first light-emitting element based on the first speed-related information and adjusts the timing of the light emission of the second light-emitting element based on the second speed-related information.
