Abstract
An image forming apparatus includes a laser device, a sensor, and a control unit. The laser device emits laser light which is reference for image forming. The sensor detects the laser light emitted from the laser device. The control unit changes an output direction of the laser light emitted from the laser device if the laser light is not detected by the sensor.
