ABSTRACT:
A cleanerless image forming method for scattering toner remained on an image carrier after transfer by a memory removing member and recovering the same at a developing section, when a power switch is turned on or when jam occurs, includes steps of applying a predetermined voltage to a transfer unit to charge the surface of an image carrier to a predetermined potential and making a potential of a memory removing member lower than a charged potential of the surface of the image carrier whereby toner remained on the memory removing member is redeveloped on the image carrier.
