Stage: PROBLEM TO BE SOLVED: To improve assembling workability by enabling an identifier of an exposure head to be visually recognized and detected after assembling the exposure head to an image forming apparatus.SOLUTION: An image forming apparatus comprises: a photoconductor; an exposure head that has a substrate on which light-emitting chips having a plurality of light-emitting elements are arranged in an axial direction of the photoconductor, a lens array in which lenses for converging light emitted from the light-emitting elements are arranged in the axial direction of the photoconductor, and a holding member for holding the substrate and the lens array, and that exposes the photoconductor; an identifier provided on the exposure head and for identifying the exposure head; and an opening that is formed on a front side in a longitudinal direction of the image forming apparatus, which matches the axial direction of the photoconductor, and through which the photoconductor is inserted into and removed from the image forming apparatus in the axial direction. The holding member is provided with an attachment portion to which the lens array is attached, and has a facing surface that faces the photoconductor over the longitudinal direction of the image forming apparatus. The identifier is provided in a region of the facing surface in front of an end surface on the front side in a longitudinal direction of the lens array attached to the attachment portion.SELECTED DRAWING: Figure 7 (Grant)
