Optical element holder, light scanning unit, and image forming apparatus with accommodation for heat-related dimensional changes of optical element
Abstract:
An optical element holder is provided with a holding frame having a side surface provided spaced apart by a specific distance from an end portion of the correction lens in a longitudinal direction by deeming a light scanning direction as the longitudinal direction and holding the correction lens so as to cover the correction lens except for at least an incident portion and an exiting portion of light, and a pushing member that pushes the correction lens toward the holding frame, so that displacement in the light scanning direction due to heat of the optical element is lessened.
