PROBLEM TO BE SOLVED: To prevent the deterioration of image quality by preventing color mixture at the exposing of a photosensitive material, and also, to markedly reduce labor and a cost at the installing of an optical selection film inside light mixing components, as for an image exposing device for mixing light of different wavelength emitted from a plurality of light emitting element arrays by using the light mixing components, and then, exposing the photosensitive material. SOLUTION: As for the image exposing device provided with a plurality of light emitting elements arrays 21 to 23 for separately emitting 1st to 3rd light having mutually different wavelength, a light mixing means 30 for receiving the 1st to 3rd light and forming linear outgoing light, the light mixing means 30 is provided with a 1st light selection film 35 and a 2nd light selection film 37 for selectively transmitting or reflecting the light according to wavelength. And the device is provided with a wavelength changing means for cutting a wavelength range included in a differential wavelength range between a wavelength when the switching of P-polarized light from transmission to reflection is performed and a wavelength when the switching of S-polarized light from transmission to reflection is performed in the 1st light selection film 35 and/or the 2nd light selection film 37 from the 1st to 3rd wavelength range.
