Abstract
An image forming apparatus comprises an image carrier, a main charger for charging the image carrier, an exposure unit for exposing the image carrier to form a latent image thereon, developing unit for developing the latent image to form a developed image on the image carrier with a developing agent, the developing unit is provided so that there is a gap between it and the image carrier, and a transferring charger for transferring the developed image onto a sheet-like material. A bias voltage is applied across the developing unit and image carrier to cause the developing agent to transfer from the developing unit to the latent image via the gap, and to cause the residual developing agent remaining on the image carrier after the developed image transferring by the transferring charger to transfer to the developing unit via the gap.
