| 英文摘要 | PURPOSE:To eliminate the influence of a light quantity fluctuation caused by heating and to obtain a prescribed light quantity extending from a start point to an end point of each scanning line by providing a light transmittivity control means for leading the light quantity corresponding to a wavelength fluctuation of a laser beam in the prescribed direction, in a laser beam optical path of an image forming optical system. CONSTITUTION:In a laser beam optical path of an image forming optical system 8, a light transmittivity control means 21 for leading the light quantity corresponding to a wavelength fluctuation of a laser beam in the prescribed direction is provided. In this state, when a cavity temperature of a semiconductor laser rises, wavelength of the laser beam is fluctuated to a long wavelength side, and an output of a semiconductor laser is provided with the quality for lowering the light quantity. Accordingly, by using that which is provided with a characteristic for increasing the transmittivity in accordance with an increase of wavelength of the laser beam, as a transmission filter 21 installed through in an image forming optical system 8, the light quantity for scanning a photosensitive drum 9 can be held constant. In such a way, even if the light quantity of the laser beam radiated by heating of a semiconductor laser light source is fluctuated, the scanning surface is always scanned by a prescribed light quantity. |
