ABSTRACT:
A developing device includes a removing roller positioned vertically above a supplying roller and in contact with a developing roller. Positively charged toner is supplied from the supplying roller to the developing roller and then supplied to a photosensitive drum for developing an electrostatic latent image thereon. Toner remaining on the developing roller that was not supplied to develop the latent image is removed by the removing roller. Some of the toner stripped by the removing roller falls down toward the supply roller and is again supplied to the developing roller.
