Abstract
A biaxial scanning mirror for an image forming apparatus includes a first wafer, a second wafer, and a spacer. The first wafer includes a mirror unit, a rectangular rotating unit, a permanent magnet, and a magnetically permeable layer. The second wafer has at least two cores each surrounded by a planar coil applied with an AC current for switching magnetic polarization of the cores such that the cores are attracted to or repelled from the rotating unit alternatively, thereby driving the rotating unit to rotate.
