The toner is rubbed by a brush by the rotation of a brush roller 21. and a supply roller 23, thereby being negatively electrified by the friction to be held on the brush. The toner having a sufficient charge amount is supplied to the aperture and thereabouts while being held in the space in non-contact state by a repulsive force from the electric field curtain. The toner having a small charge amount is not susceptible to a repulsive force from the electric field curtain, thus repeatedly being disturbed and vibrated by the action of the electric field and electrified by the friction with an exciter. The toner provided with sufficient charges is subjected to the repulsive force of the electric field curtain to be suspended again in the space and supplied to the aperture and thereabouts.
