An image forming apparatus can include a print head, a detector, a controller, and a power source. The print head includes one or more light emitting element rows, each light emitting element row composed of a plurality of light emitting elements. The detector detects the number of light emitting elements that emit light according to image data. The controller controls a driving voltage for driving the light emitting element based on a detection result. The power source supplies the driving voltage to the print head.
