Abstract:
1. An image forming device comprising: an exposure head having a latent image carrier that moves in the second direction, wherein the latent image carrier is a photoconductor drum rotatable in the second direction; a detection section that detects a moving time that the latent image carrier takes to move from a first position to a second position in the second direction; a control section that controls an emission time interval between an emission timing of the first light emitting element and an emission timing of the fourth light emitting element based on a detection result of the detection section, thereby aligning a latent image formed by emitting of the first light emitting element, a latent image formed by emitting of the second light emitting element, and a latent image formed by emitting of the fourth light emitting element in the first direction on the latent image carrier; a drive source; and a gear that transmits driving power from the drive source to the photoconductor drum, wherein a distance between the first and second imaging optical systems in the second direction is longer than a distance obtained by multiplying a velocity variation period of the photoconductor drum by an average velocity of the photoconductor drum.
