To stabilize distances to an auxiliary scanning direction of two spots formed by two light emitting elements arranged in the auxiliary scanning direction.
This image forming device includes: a latent image carrier moving in a first direction; an exposure head having a first light emitting element, a second light emitting element arranged in a first direction of the first light emitting element and an imaging optical system imaging light emitted by the first light emitting element to irradiate the latent image carrier with first light and imaging light emitted by the second light emitting element to irradiate the latent image carrier with second light; and an adjustment section adjusting timings when the first and second light emitting elements emit light. When a distance in the first direction between the first light and the second light formed by making the first and second light emitting elements simultaneously emit light is denoted by D0, by making light an emitting timing T2 of the second light emitting element different from a light emitting timing T1 of the first light emitting element, the first light and the second light are formed at a distance D1 different from the distance D0 in the first direction.
