A dust-screening member arranged in front of an image forming unit that holds an image forming element configured to generate an optical image, is formed into a box shape that includes a plate-shaped polygonal light transmitting part that passes light entering from or to the image forming element, and a plurality of foot portions that tilt by a predetermined angle and extend from all sides of the light transmitting part or portions near all sides in a direction in which the image forming unit is located. The light transmitting part and the plurality of foot portions are formed using the same material. A vibrating member is fixed to at least one of the plurality of foot portions. The dust-screening member is held by an elastic force of an elastic member arranged between the plurality of foot portions and a support member configured to support the plurality of foot portions.
