Abstract
An image forming apparatus for collecting, through a developing device, and reusing remaining toner remained on a photosensitive drum, as an image carrier, for forming an electrostatic latent image, without being transferred to a transfer material, includes a toner uniforming member disposed between locations for a charging process and for an exposing process, for making the toner remained on the photosensitive drum during a transferring process adhere slightly and uniformly to the photosensitive drum. The toner uniforming member eliminates the remaining toner remained on the photosensitive drum temporarily, and is applied with a necessary voltage for making the remaining toner eliminated temporarily adhere to the surface of the photosensitive drum again.
