Abstract:
1. A vibrating device comprising: a holding member configured to hold an image forming element having an image surface in which an optical image is generated; a dust-screening member including a plate-like light transmitting portion which has a polygonal shape including a plurality of sides and is configured to permit the transmission of one of light coming from the image forming element and light coming into the image forming element, and at least one plate-like side wall portion which tilts as much as a predetermined angle and extends from at least one side of the plate-like light transmitting portion; and a vibrating member fixed to one plate-like side wall portion among the at least one plate-like side wall portion and configured to apply a vertical vibrational amplitude to the surface of the plate-like light transmitting portion, wherein the plate-like light transmitting portion and the at least one plate-like side wall portion are formed to have a substantially uniform thickness by use of the same material, the plate-like light transmitting portion is positioned in front of the image forming element, the one plate-like side wall portion provided with the vibrating member is fixed to the holding member at a position other than a position to which the vibrating member is fixed, in the polygonal shape forming the light transmitting portion, a side wall portion does not extend from at least sides of both sides adjacent to a side from which the plate-shape side wall extends, and the dust-screening member is fixed to the holding member at a position other than a portion to which the vibrating member is fixed.
