An electrophotographic image forming apparatus increases resolution in the main scanning direction. To accomplish this, the image forming apparatus includes a light source having N light-emitting portions each configured to emit a light beam based on an input image signal, an input unit which inputs image data, a signal generation unit which extracts one-scanning image data corresponding to one scanning based on the input image data, and generates N image signals that form one-scanning image data upon composition, and a scanning control unit which scans a single track on a photosensitive body by N light beams emitted by the light source to form a latent image corresponding to one-scanning image data on the photosensitive body.
