Claim:
1. An image forming apparatus comprising: a photoreceptor to be rotated; an exposure unit including a light emitting array including a plurality of light emitting elements configured to emit light and a lens array including a plurality of lenses configured to focus the light emitted from the plurality of light emitting elements on the photoreceptor, wherein the plurality of light emitting elements is arranged in a direction transverse to a rotation direction of the photoreceptor, and the exposure unit forms an electrostatic latent image on the photoreceptor by irradiating light emitted from each of the light emitting elements via the lens array; a developing unit configured to develop the electrostatic latent image with a toner; a driving unit configured to drive the plurality of light emitting elements based on driving data corresponding to each of the plurality of light emitting elements; a data generation unit configured to generate the driving data corresponding to each of the plurality of light emitting elements by using filters, each of which corresponds to one of the plurality of light emitting elements, wherein each of the filters is set for correcting a potential distribution on the photoreceptor due to a spot shape of light emitted from each of the plurality of light emitting elements on the photoreceptor, and wherein the data generation unit is configured to generate the driving data for a target pixel with respect to each of the plurality of light emitting elements based on data generated by applying the filter, which corresponds to one of the plurality of light emitting elements, to pixel data for the target pixel and pixel data for adjacent pixels adjacent to the target pixel.
