The image forming apparatus includes: plural photosensitive members; plural exposing units opposed to the photosensitive members, respectively, each of the exposing units including a plurality of light emitting elements arranged in a first direction; and a body frame which is provided at both sides of the exposing units in the first direction. Each of the exposing units includes: a gap maintaining member which abuts a respective one of the photosensitive members to define a distance between the exposing unit and the photosensitive member; a first-direction positioning portion which abuts the body frame in the first direction to position the exposing unit in the first direction; and a second-direction positioning portion which abuts the body frame in a second direction perpendicular to the first direction and an exposing direction of the light emitting elements, to position the exposing unit in the second direction.
