Abstract:
1. An exposure device comprising: an exposure member that includes a plurality of light-emitting devices arranged along a first direction, which is an axial direction of an image carrier that rotates, the exposure member exposing the image carrier to light by emitting light in a second direction, which is a direction from the plurality of light-emitting devices to the image carrier; an abutment member that includes a contact portion that comes into contact with the exposure member, the abutment member causing the exposure member to abut against the image carrier by pressing the exposure member in the second direction using the contact portion; and an elastic member that is interposed between the exposure member and the abutment member, the elastic member being elastically deformable in a direction in which the exposure member and the abutment member approach or recede from each other, wherein the exposure member includes a first protrusion and a second protrusion, the first protrusion protruding in the second direction toward the abutment member and being in contact with the contact portion of the abutment member, the second protrusion protruding in the second direction toward the image carrier, wherein the abutment member causes the second protrusion of the exposure member to abut against the image carrier by pressing the first protrusion of the exposure member using the contact portion, and wherein the elastic member is disposed adjacent to the contact portion of the abutment member and the first protrusion of the exposure member.
