とする画像形成装置。 A transfer means for transferring the toner image on the photoreceptor onto a transfer material, an optical charge removal means for irradiating light onto the photoreceptor after transfer to remove the electric charge, and a toner image remaining on the photoreceptor after transfer. In an image forming apparatus having a cleaning means for removing untransferred toner, and in which the optical charge eliminating means is disposed in a step before the cleaning means, the optical charge eliminating means is removed during the time when the toner image is transferred onto the transfer material. An image forming apparatus characterized in that an image forming apparatus is provided with a charge removal light amount adjusting means for reducing the amount of light irradiated onto the photoreceptor.
