  • 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.

  • Patent number: 11054760
    Abstract: According to one embodiment, an image forming apparatus includes a light emitting element array, a photosensitive member, a transparent member, a gap spacer, and a biasing member. The light emitting element array includes a plurality of light emitting elements. The photosensitive member forms a latent image by being exposed by light emitted from the light emitting element array. The transparent member is positioned between the photosensitive member and the light emitting element array. The transparent member has a relative position fixed with respect to the light emitting element array, and transmits the light emitted from the light emitting element array. The gap spacer keeps a distance between the photosensitive member and the transparent member constant. The biasing member biases the transparent member toward the photosensitive member.
