PURPOSE:To provide an image forming device which can emit light from respective light emitting accurately and without forming any spaces and form a latent of high image quality on a sensitive film, CONSTITUTION:An image forming device is disposed inside a transparent cylindrical body 6a coated with a sensitive film 66 on the outer surface, and emits light from inside the transparent cylindrical body 6a to the sensitive film 6b and forms a latent image on the sensitive film 6b. The device consists of a lens plate 2 on which a plurality of lenses 5 are disposed and supported in the straight line shape at are disposed and supported in the straight line shape at the given intervals and a base plate 1 on which a number of line shape, and the lens plate 2 and the base plate 1 are combinedly fixed in a manner of making respective lenses 5 and respective pixel arrays 4 corresponding one- to-one. The thermal expansivity of the lens plate 2 anal the expansivity of the base plate 1 are made substantially same to the thermal expansivity of the transparent cylindrical body 6a. |
