Abstract
A developing apparatus using a developer carrier which is capable of forming microfields on the surface of the carrier. A great amount of sufficiently charged one-component developer is deposited on the surface of the developer carrier by the microfields and transported to a developing region to be supplied to an electrostatic latent image. The developer carrier has a plurality of surface portions, each having a particular characteristic, such that at least one surface portion holds a first charge while at least another surface portion holds a second charge that is equal to and of an opposite polarity to the first charge.
