Light-orientation adjusting unit, optical writing unit having light-orientation adjusting unit, and image forming apparatus having optical writing unit

摘要

A light-orientation adjusting unit for use with a light-receiving member includes an optical unit, a posture control unit, a first unit supporter, and a second unit supporter. The optical unit passes through a light beam toward the light-receiving member. The posture control unit controls the posture of the optical unit to adjust an inclination of scanning line to be formed on the light-receiving member by the light beam. The first unit supporter regulates a movement of the optical unit within a given range by contacting the first unit supporter to the optical unit. The second unit supporter regulates a movement of the optical unit within a given range by contacting the second unit supporter to the optical unit. The first unit supporter including a first biasing member and second unit supporter including a second biasing member are disposed on a first and second ends of the optical unit, respectively.
