Abstract
PURPOSE:To miniaturize a deflecting system by obtaining such a constitution that two laser beams are led to the deflecting system through mirrors or prisms. CONSTITUTION:A laser unit 2M is arranged closer to a sheet a distance L' than a laser unit 2C is. Here, the height of the mirror 10C as an optical deflecting member is a distance from the sheet in the vertical direction, and the height is set, so that the mirror 10C reflects the laser beam 3C and blocks no laser beam 3M. Thanks to this constitution, the interval L between beams satisfies L'<L, whereby the width H of the polygonal mirror R as a deflecting system can be minimized. Thus the interval between a pair of two beams can be minimized to scale down the deflecting system 4. Its irregularity of rotation and surface blurring can be reduced to obtain the high performance laser color printer.
