摘要： Disclosed herein is an image forming apparatus that emits a beam corresponding to an image onto an image-projected object to allow the image to be formed thereon. The apparatus includes: a lamp; a lamp power supply; a lens; a brightness sensor that measures a lamp brightness; a memory that stores, as a reference brightness value, the lamp brightness measured at a first time when brightness of the beam on the image-projected object has reached a target value; and a control circuit. At a second time, the control circuit performs first control of generating or updating and storing correspondence information. At a third time, the control circuit performs second control of identifying a level of an output power of the lamp power supply corresponding to the reference brightness value, and driving the lamp power supply with the identified level of the output power.
