Abstract
An exposure device includes a transmissive member and a shutter. The transmissive member allows passage therethrough of a light beam directed toward a scanning object. The shutter is mounted so as to be pivotable around a pivot shaft between a closed position and an open position. The shutter has a first member and a second member. In the closed position, the first member shields the transmissive member, and, in the open position, unshields the transmissive member so as to allow the light beam to pass through the transmissive member. In the closed position, the second member is positioned above the first member so as to extend at least beyond peripheral ends, including a free end, of the first member.
