An exposure device includes: an optical system member that causes light irradiated from a light emitting element to converge; an optical system support part that supports the optical system member; and a fixing member for fixing the optical system member to the optical system holding part. An elongation of the fixing member is in a range of 40% to 80% inclusive.

Exposure device and image forming device having a fixing member for fixing an optical system member

An exposure device includes: a substrate on which a plurality of light emitting elements are mounted; an optical system that converges light irradiated from the light emitting elements onto a photosensitive surface; a holding member that holds and fixes the substrate; a support member that supports the optical system and the holding member; a first adhesive member that is provided between the substrate and the holding member; and a second adhesive member that is provided between the holding member and the support member, wherein the first adhesive member has higher elongation and lower hardness than the second adhesive member.
