Abstract
In a developing device, a developing coating layer of each of a plurality of developing rollers has been formed by a dipping method in which a developing base body is dipped in a liquid in a state where the developing base body is in a vertical attitude such that a first end of the developing base body faces down and a second end of the developing base body faces up. The plurality of developing rollers are arranged from an upstream side to a downstream side in a rotation direction of an image-carrying member in such a manner that directions faced by the first end and the second end of each of the plurality of developing rollers are alternately reversed.
