ABSTRACT:
An optical writing device that writes electrostatic latent images on an image carrier by irradiating and scanning the image carrier with an optical beam includes an optical element, a support housing configured to support members constituting the optical writing device, a pair of optical-element holding members opposing each other in a principal scanning direction and arranged in the support housing, and a displacing member configured to displace at least one of the pair of optical-element holding members relatively to the support housing on a plane perpendicular to the principal scanning direction. The optical-element holding member is made of a material having a coefficient of linear expansion smaller than that of the support housing.
