Image forming apparatus and exposure device

Abstract

An image forming apparatus includes an image carrier that rotates; and an exposure unit that includes multiple light emitters, a holding unit, and first contact portions, the multiple light emitters being arranged along a rotation axis direction of the image carrier, the holding unit holding the multiple light emitters, the first contact portions being positioned on the holding unit so as to sandwich the multiple light emitters therebetween, the exposure unit exposing the image carrier to light. While the image carrier is being mounted on an apparatus body, the exposure unit is moved away from the image carrier in an optical axis direction of the exposure unit as a result of the first contact portions coming into contact with the image carrier, and the exposure unit and the image carrier are positioned as a result of the first contact portions coming into contact with the image carrier.
