A medium for preventing forgery having a hologram layer and at least one patterned optically anisotropic layer,wherein the patterned optically anisotropic layer has two or more regions comprising different birefringence property, andwherein all the regions are formed of the same composition. The image processing device can execute image processing on digital image data to reduce a coarse look caused by film particles without blurring edges in the image. Other features include electrical contacts that are relatively thin conductors on the order of 0. The first reflection member is disposed nearer to the first photosensitive member than the second laser beam projected from the deflection unit, whereas the second reflection member is disposed remoter from the first photosensitive member than the second laser beam projected from the deflection unit. The anterior surface and the posterior surface are approximately parallel to each other. A wall is attached to the outer peripheral edge and extends downwardly from the annular member.
