摘要： 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.

摘要： A curvature correction device used in an optical scanning unit includes a holder and a pushing unit. The optical scanning unit includes a light beam emitter to emit a light beam, a deflection unit to deflect the light beam in a main scanning direction, and a reflection mirror to reflect the light beam. In at least one embodiment, the curvature correction device includes a holder and a pushing unit. The holder holds the reflection mirror in a state in which the reflection mirror is forcibly bent in a first direction. The pushing unit pushes the reflection mirror held by the holder to bend the reflection mirror in a second direction opposite the first direction. The curvature correction device corrects the curvature of the main scanning line by adjusting an amount at which the pushing unit pushes the reflection mirror. The holder has a stiffness larger than the reflection mirror.

摘要： An optical scanner for writing an electrostatic latent image on an image carrier includes a scanning optical system that forms an optical scanning path, a pair of optical detecting units arranged at two positions on the optical scanning path for detecting a write-start position and a write-end position to measure a time for scanning from the write-start position to the write-end position, and an optical housing that houses at least the scanning optical system and the optical detecting units. The optical detecting units are mounted on the optical housing via an intermediate member having a thermal expansion coefficient smaller than that of the optical housing.
