  • Publication number: 20210294240
    Abstract: An image forming apparatus includes a photoconductor, light emitting elements, a developing device, a fixing device, and a controller. The photoconductor is charged. The light emitting elements form light spots on the photoconductor in order to form an electrostatic latent image on the photoconductor, and are provided to have a first distance with each other in a main scanning direction. The developing device develops an electrostatic latent image on the photoconductor to a toner image. The fixing device fixes the toner image to a sheet. The controller causes the light emitting elements to form first light spots on the photoconductor, causes the photoconductor to move toward the light emitting elements by a second distance shorter than the first distance in a sub-scanning direction orthogonal to the main scanning direction, and causes the light emitting elements to form second light spots on the photoconductor.
