<p><P>PROBLEM TO BE SOLVED: To provide a microelectromechanical modulation device enabled to actively reduce the oscillation of a movable portion, to provide a microelectromechanical modulation device array, and to provide an image forming apparatus, and thereby to speed up a switching operation. <P>SOLUTION: A microelectromechanical modulation device 100 comprises: a movable portion 27, which is supported to be elastically and bi-directionally displaced and which has a modulation function; and a plurality of driving sources operative to apply a physical action force to the movable portion 27, wherein when the movable portion 27 is displacement-driven in a first direction, a physical action force for suppressing oscillation of the movable portion is applied to the movable portion 27 by the driving source in a second direction different from the first direction by the drive sources while the movable portion 27 is transited in the first direction. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
