摘要： PROBLEM TO BE SOLVED: To provide an image forming apparatus introducing a transfer system to transfer a toner image formed on the surface of an image carrier 2 to a recording medium 5c, then, obtain an image formation object, wherein such a failure is suppressed that toner-scattering occurs before a toner image formed on an image carrier is transferred, without making the image forming apparatus large in size.
SOLUTION: Such a digital photoreceptor drum is used as an image carrier 2, that is an exposure source/latent image formation integrated type digital photoreceptor drum including a light emitting element matrix layer and a photoreceptor layer layered on the light emitting element matrix layer, and charged by a charging means. At a pre-transfer exposure, the light emitting pixel portion of the light emitting element matrix layer corresponding to the non-image formation part of the photoreceptor layer is made to emit light, and at least the non-image formation part on the photoreceptor layer is exposed several times or continuously, related to the same area.
