光量制御装置、露光装置、画像形成装置および光量制御方法
Document Type and Number:
Japanese Patent JP4769640
Kind Code:
B2
Abstract:
A light scanning apparatus includes a plurality of light sources. A detection unit detects the light power of a light beam output from at least one of the plurality of light sources. A control unit controls the driving current of at least one selected light source on the basis of the detection result by the detection unit such that the light power of the selected light source equals a target light power. The light source is selected from the plurality of light sources on the basis of the light-emitting characteristic of each light source. The control unit controls, on the basis of the driving current of the selected light source, the driving currents of light sources which remain unselected in the plurality of light sources.
