OPTICAL SCANNER AND IMAGE FORMING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a compact optical scanner capable of preventing stray light from occurring due to the front surface pressing member of a reflection member. SOLUTION: The reflection member 124 for reflecting a laser beam is supported in an interposing state where its posture is freely adjusted by the front surface pressing members 230 and 231 and back surface supporting members 225 and 226, and measures to prevent the stray light are taken for the surfaces of the members 230 and 231.
