Abstract
An image forming apparatus including a detector, a write controller, and a light controller. The detector detects, with an optical sensor, an edge of a recording medium in a direction perpendicular to a reading medium convey direction. The write controller shifts an image write position in the direction perpendicular to the recording medium convey direction on the basis of a detection result of the detector. The light controller controls a light emission amount of the optical sensor to set an output of the optical sensor to a predetermined value at a predetermined portion in an area where the detection result of the optical sensor is effective.
