Abstract

A light beam scanning optical apparatus which writes two lines at one scan on a photosensitive member with light beams emitted from two light sources. A light source unit of the apparatus has a first movable retainer block which retains a first laser diode and a second movable retainer block which retains a second laser diode. The second movable retainer block becomes adjustable two-dimensionally on a base block by loosening screws which fit the second movable retainer block to the base block.
