    • An optical scanner includes a light source, an optical element, a deflector, a casing, and a first cover. The deflector deflects the light beam emitted from the light source to scan a photoreceptor through the optical element. The casing includes an upper opening, walls including a transparent plate defining a deflector compartment to accommodate the deflector, and an optical element mounting portion to accommodate the light source and the optical element. The first cover covers the upper opening of the casing and includes a recessed portion recessed toward the bottom of the casing and including a first opening at the bottom thereof facing the deflector. The recessed portion and the walls are directly or indirectly connected to define a single continuous space isolating the deflector compartment from the optical element mounting portion. The recessed portion and the deflector compartment communicate via the first opening.
    • 光学扫描器包括光源,光学元件,偏转器,壳体和第一盖。 偏转器使从光源发射的光束偏转以通过光学元件扫描感光体。 壳体包括上部开口,包括限定用于容纳偏转器的偏转器隔室的透明板的壁和用于容纳光源和光学元件的光学元件安装部分。 第一盖覆盖壳体的上部开口,并且包括朝向壳体的底部凹陷的凹部,并且包括在其底部处面向偏转器的第一开口。 凹陷部分和壁直接或间接连接以限定将偏转器隔室与光学元件安装部分隔离的单个连续空间。 凹陷部分和偏转器室通过第一开口连通。
