In an image forming apparatus, a plurality of light emitting device array units for drawing image data on a photoconductor are arranged in a main scanning direction corresponding to an axial direction of the photoconductor with staggered positioning in a sub-scanning direction. The image forming apparatus includes a ratio setting unit configured to set a ratio of fine size adjustment for finely adjusting a size of the image data, a computing unit configured to compute a displacement of the image data responsive to the ratio of fine size adjustment set by the ratio setting unit, and a fine size adjustment unit configured to change intervals of occurrences of line synchronizing signals in response to the computation by the computing unit.
