Abstract
In a developing apparatus, a conveyor for conveying developer particles supplied from developer supplying means defines a gap with the surface of a photosensitive body. A developer supplying passage for conveying the developer particles is provided between the developer supplying means and the gap. The developer supplying passage is defined by the conveyor and an electrode plate provided at a predetermined interval with the conveyor. An alternating electric field is applied to the developer supplying passage by an A.C. power source to reciprocate the developer particles between the conveyor and the electrode plate, thereby sufficiently and uniformly charging the developer particles by friction.
