Abstract
A plane mirror is disposed in an optical path after a polygon mirror which deflects laser light. Incident light to and reflected light on the polygon mirror has no angle in an auxiliary scanning direction and the polarization direction of laser light is inclined relative to a plane (deflection plane) including the incident light to and the reflected light on the polygon mirror. An inclination angle and inclination direction of the light deflection direction of the laser light, an inclination angle of the plane mirror are configured so as to satisfy predetermined conditions. With such a configuration, a change in reflectance on the polygon mirror accompanying a change in deflection angle can be cancelled or alleviated by a change in reflectance on the plane mirror accompanying the change in deflection angle, and a difference in light quantity distribution on a photosensitive member on the left and right sides thereof is alleviated in comparison with a difference in reflectance to be caused by the polygon mirror.
