| abstract | (57) [Abstract] [Purpose] By changing the thickness of the reflection-increasing film layer of the reflection mirror arranged in the exposure optical system according to the incident angle of the light flux, the spectral reflection characteristic is substantially eliminated regardless of the incident angle. It is made uniform to prevent color unevenness and density unevenness from occurring on the image formed on the printing paper. [Structure] The reflection mirror 1 includes an Al layer 3 on a glass plate 2. And a reflection enhancing film layer 4 made of MgF 2 or SiO 2 . The reflection enhancing film layer 4 is a reflection mirror 1. The thickness gradually decreases from one end Q toward the other end R, and the end Q has a thickness t 1 and the end R has a thickness t 2. There is. The increased reflection film layer 4 has substantially the same spectral reflection characteristics for each light flux incident on the reflection mirror 1 from the exit pupil position (imaging lens position) P regardless of the incident position (incident angle). It is formed to a thickness. |
