## Abstract

An image forming device includes a photoconductive body, an exposure unit configured with a plurality of light emitting elements aligned in a predetermined direction, the exposure unit being adopted to expose the photoconductive body to light emitted by the light emitting elements, a frame configured to support both sides of the exposure unit in the predetermined direction, the frame having a reference portion configured to position the exposure unit in the predetermined direction in contact with an end of the exposure unit in the predetermined direction, and a pressing member provided to one of the frame and the exposure unit, the pressing member being configured to press the end of the exposure unit against the reference portion.

## Claims

### Claim 1

An image forming device, comprising:
a photoconductive drum;
an exposure unit having a plurality of light emitting elements aligned in a first direction, a first end portion and a second end portion opposite to the first end portion in the first direction, the exposure unit facing the photosensitive drum in a second direction perpendicular to the first direction and being configured to expose the photoconductive drum;
a first frame which is provided adjacent to the first end portion of the exposure unit and which has a reference portion configured to position the exposure unit in the first direction, the reference portion being in contact with the first end portion of the exposure unit in the first direction;
a second frame, the exposure unit being disposed between the first frame and the second frame in the first direction; and
a pressing member provided to one of the first frame and the exposure unit, the pressing member being configured to press the first end portion of the exposure unit against the reference portion in the first direction.
