Abstract
An image recording apparatus has a photochromic photosensitive member with a light transmittance that is variable dependent on the light applied to it from an original that has been illuminated by a first light source. A second light source, which emits a light that the photochromic photosensitive member is insensitive to, is then used to form an electrostatic latent image on an uniformly charged photosensitive sheet with the photosensitive sheet being carried on the surface of a transfer drum past one or more developing devices in order to make the electrostatic latent image on the photosensitive sheet a visible image. A mask member film may alternatively be used between an exposure light source and the photosensitive sheet.
