    Abstract: A protruding locking pawl is provided at an end of a light guide which corresponds to a first light input surface. A recessed locking portion is formed in a frame so that the locking pawl can be locked in the locking portion. A light blocking member is slidably loosely inserted into a position where the light blocking member covers a longitudinal end of the light guide which corresponds to a second light input surface. Even if expansion and contraction occurs in the longitudinal direction of the light guide, the design dimensions of a first gap A and a second gap B can be maintained; the first gap A is formed between the first light input surface and a first light source, and the second gap B formed between the second light input surface and a second light source. Therefore, possible leakage current can be prevented.

The optical scanner includes: an incident optical system which at least comprises: a light beam emission device configured to emit a light beam; and a cylindrical lens configured to condense the light beam emitted from the light beam emission device, and a scanning optical system which at least comprises: a light deflecting device configured to reflect the light beam having passed through the cylindrical lens to deflect the light beam in a main scanning direction for scanning the photosensitive member; and a scanning lens configured to focus the light beam deflected by the light deflecting device on the photosensitive member to form an electrostatic latent image thereon. The incident optical system and the scanning optical system are divided by a light shielding wall.
