る画像形成装置。[Scope of Claim for Utility Model Registration] A flash exposure system 3 that forms a latent image on the photosensitive material 2 by exposing the target original 1 to the entire surface at once, and the photosensitive material 2
It has a slit exposure system 5 which shares the upper imaging lens 4 with the flash exposure system 3 and sequentially forms a latent image on the sensitive material 2 by scanning the original by light irradiation, and the respective exposure systems 3 and 5 In an image forming apparatus that visualizes a latent image formed on a photosensitive material 2 in a flash exposure system 3, the aperture of the imaging lens 4 is
An image forming apparatus characterized by comprising an aperture switching mechanism 7 that switches between exposure using a slit exposure system 5 and exposure using a slit exposure system 5.
