ABSTRACT:
A light intensity control apparatus includes a beam generation unit for generating a beam for image recording, a detection unit for detecting a light intensity of the beam generated by the beam generation unit, and a control unit for controlling the light intensity of the beam generated by the beam generating unit on the basis of the detection output from the detection unit. The control unit causes the detection unit to execute a monitor operation of the light intensity of the beam during an image recording period by the beam, and changes, during a non-image recording period, a light intensity control value of the beam on the basis of the light intensity of the beam monitored during the image recording period.
