<p><P>PROBLEM TO BE SOLVED: To provide an optical scanner in which axis tilt is certainly corrected, and a stable laser light spot form is obtained and a superior image quality is obtained. <P>SOLUTION: The optical scanner includes a rotary polygon mirror 4, which deflects and scans laser light; a circuit substrate 12 for driving a deflector 5 having the rotary polygon mirror 4; a shaft end part 15, which is projected farther out than the face which is located opposite to the side of the face of the circuit substrate 12 on which the rotary polygon mirror 4 is disposed; an optical box 8 in which the deflector 5 is fixed; and a correction member 20, which is fixed in a state where the axis tilt of the rotary shaft 11 of the rotary polygon mirror 4 is corrected by pressurizing the shaft end part 15 after fixing the deflector 5 in the optical box 8. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
