Abstract
An electric field applying device is disposed in a position opposite to a surface of rotary developing device within an area defined between the surface of the developing means and a position of scratching device after the surface of the developing device passes through a developing area so as to apply an electric field in a direction in which ions having the polarity opposite to that of toner particles are separated from the surface of the developing device.
