LASER SCANNING UNIT AND IMAGE FORMING APPARATUS HAVING THE SAME

摘要

PURPOSE: The optical scan unit and image forming apparatus including the same uses the reflective mirror and the optical density rate deviation is diminished. CONSTITUTION: The light in which the deflector(34) is created from the light source(31) is leaned to the main scanning direction. The imaging lens images the slanted light as described above in the photoconductor(51). One or more reflective mirror varies the progressive direction of the light. The wavelength of the light created in the light source is approximately, 500 nm or less. The reflective mirror is arranged between deflector and imaging lens. The imaging lens is formed into the plastic material.
