摘要：
A charging method of an electrostatic image developer which makes it possible to electrically charge an insulating one-component developer or a two-component developer consisting of a toner and a carrier to a desired charged state and which comprises introducing the developer into a charging space between a pair of sheet-like charging members opposing each other in which space an alternating field is formed, and oscillating the developer by means of the alternating field for charging it. A developing method of a non-contact or contact system which develops the electrostatic image by use of the developer charged electrically by the above-mentioned charging method.
