ABSTRACT:
The light beam scanning apparatus of the present invention which is capable of recording or reading an image of high quality has a memory unit that stores datum representing the intensity of light in association with scanning density and a selector that selects said light intensity data from said memory unit according to a particular scanning density.
Therefore, when the scanning density is changed by altering the transport speed in sub-scanning direction, the intensity of the light beam emitted from a light source such as a laser is adjusted by the data which is selected by the selector from the memory unit according to the scanning density.
