A developing device including a supply member pressingly contacted with a toner carrier having a hardness which is greater than that of the supply member and smaller than a predetermined hardness. The supply member is rotated in the same direction as the toner carrier to conduct the removing and supply of toner. A plate spring-like regulation member is pressed against the toner carrier to charge the toner to a predetermined polarity and thin the toner into one or two layers.
