An electrophotographic image forming apparatus performs latent image rendering using a plurality of light sources. The electrophotographic image forming apparatus includes a rendering time control unit that controls a latent image rendering start time for each of the light sources, a scanning time control unit that controls a scanning start time for each of the light sources, a pattern forming unit that forms a pixel pattern corresponding to pixel pattern data defined in advance on a photosensitive member, and a density detection unit that detects a density of the pixel pattern formed on the photosensitive member. The rendering time control unit and the scanning time control unit respectively control the rendering start time and the scanning start time for each of the light sources using a density value detected by the density detection unit.
