Zusammenfassung:	To provide an improved mechanism for compensating for an error in an image forming range.SOLUTION: Provided is an image forming apparatus including: a photosensitive body that is driven so as to rotate; an exposure head including a plurality of light-emitting units arranged at different positions in an axial direction of the photosensitive body; the exposure head being configured to form each of pixels of an image, corresponding to an output resolution of the image forming apparatus, by means of a certain number of light-emitting units of the plurality of light-emitting units; and a control unit that, based on correction data, controls the above-described number of light-emitting units to be driven in order to form each of the pixels of the image.SELECTED DRAWING: Figure 13D 【課題】画像形成範囲の誤差を補償するための改善された仕組みを提供すること。【解決手段】画像形成装置であって、回転するように駆動される感光体と、前記感光体の軸方向において異なる位置に配置された複数の発光部を含む露光ヘッドであって、前記画像形成装置の出力解像度に対応する画像の画素の各々を前記複数の発光部のうちのある数の発光部により形成する当該露光ヘッドと、補正データに基づいて、前記画像の前記画素の各々を形成するために駆動される発光部の前記数を制御する制御部と、を備える画像形成装置が提供される。【選択図】図１３Ｄ
