装置。In an image forming apparatus using a halogen lamp as a light source for exposing an original, the exposure light reflected or transmitted from the original surface is projected as a slit image onto the recording medium surface by an imaging optical system. A slit plate is disposed in the optical path from the original illumination unit to the recording medium so that the exposure light passes through the slit hole 13 of the slit plate and reaches the surface of the recording medium.
The left light shielding plate, the center light shielding plate, and the right light shielding plate are arranged so that the opening width of the central region along the length of the slit hole 13 and the opening width of both end side regions can be independently and arbitrarily adjusted in the slit plate.
An exposure device characterized by comprising three movable light shielding plates.
